Was the allocation sequence random?
rct_d1_1
|
The document explicitly states that computer-generated random numbers were used for the allocation sequence, which is a recognized method for adequate random sequence generation. The description is clear and unambiguous, meeting the criterion for low risk of bias.

low risk | |
|
Was the allocation sequence concealed until participants were enrolled and assigned to interventions?
rct_d1_2
|
The document states that 'The scholars involved in randomization, distribution and administration of study articles were independent from the investigators' and that 'Computer generated random numbers were utilized for the study. Block size was 4.' However, there is no explicit description of the allocation concealment method (e.g., central allocation, sequentially numbered sealed envelopes, or any other mechanism to ensure that the allocation sequence was concealed until participants were enrolled and assigned). The text does not confirm that those recruiting participants were unaware of the upcoming allocation. Therefore, while the randomization process is described, the concealment of allocation is not explicitly addressed, leading to some concerns about potential selection bias.

|
Were participants aware of their assigned intervention during the trial?
rct_d2_1
|
The document explicitly states the study was 'double-blind' but provides no description of the specific blinding procedures used for participants. Without details on how blinding was implemented (e.g., identical capsules, placebos, or other methods), it is impossible to confirm that participants were unaware of their assigned intervention. The available evidence is insufficient to rule out potential bias.

|
Were carers and people delivering the interventions aware of participants' assigned intervention during the trial?
rct_d2_2
|
The document states the study was 'double-blind' but provides no explicit description of blinding procedures for carers or personnel delivering the interventions. The only relevant statement is that 'scholars involved in randomization, distribution and administration of study articles were independent from the investigators,' which addresses allocation concealment but not blinding of care providers. Without further detail on how blinding of personnel was achieved or maintained, there is insufficient evidence to confirm low risk.
|
some concerns | |
|
Were there deviations from the intended intervention that arose because of the experimental context?
rct_d2_3
|
The document describes a double-blind, randomized design with independent personnel for randomization and administration, which suggests efforts to minimize deviations due to the experimental context. However, there is no explicit description of measures to ensure blinding integrity (e.g., placebo matching, blinding assessment), no mention of whether co-interventions were prohibited or monitored, and no details on adherence monitoring or management of protocol deviations. The absence of these details raises concerns about potential deviations from intended interventions that could arise from the trial context.

|
Were data for this outcome available for all, or nearly all, participants randomized?
rct_d3_1
|
The document explicitly states that no patients dropped out of the study, indicating complete outcome data for all randomized participants. The CONSORT flow chart is referenced, and the text confirms that all 68 patients completed the study without any adverse effects or dropouts. This directly addresses the criterion of data availability for all or nearly all participants.
|
low risk | |
|
Is there evidence that the result was not biased by missing outcome data?
rct_d3_2
|
The document explicitly states that no patients dropped out of the study, which directly addresses the criterion of missing outcome data. The statement is unambiguous and indicates complete follow-up for all 68 randomized participants. There is no evidence of missing data that could bias the observed effect.
|
low risk | |
|
Could missingness in the outcome depend on its true value?
rct_d3_3
|
The document explicitly states that no patients dropped out of the study, which suggests that missingness in the outcome data is not an issue. However, the assessment of whether missingness could depend on the true value of the outcome requires detailed information about the handling of any missing data, including reasons for missingness and whether those reasons could be related to the outcome. The document does not provide any information about missing data mechanisms, sensitivity analyses, or statistical methods to address potential bias from missing data. Therefore, while the claim of no dropouts is clear, the lack of detail on how missing data (if any) were handled or whether any data were missing at all leaves some uncertainty.
|
some concerns | |
|
Was the method of measuring the outcome inappropriate?
rct_d4_1
|
The document explicitly describes the measurement of the primary outcome (blood pressure) using standard operating procedures, which implies a valid and reliable method. The secondary outcomes include well-established measures such as the Hamilton Anxiety Rating Scale and lipid profiles, which are standard in clinical research. There is no evidence of an inappropriate measurement method.

Could measurement or ascertainment of the outcome have differed between intervention groups?

some concerns | |
|
Were outcome assessors aware of the intervention received by study participants?
rct_d4_3
|
The document states the study was 'double-blind' but provides no explicit description of blinding procedures for outcome assessors. While the title and methods section claim double-blinding, there is no specific statement that outcome assessors were blinded to treatment allocation. The methods mention that 'scholars involved in randomization, distribution and administration of study articles were independent from the investigators,' which implies separation of roles but does not directly address blinding of outcome assessors. Without explicit detail on who assessed outcomes and whether they were blinded, there is insufficient evidence to confirm low risk.
|
some concerns | |
|
Could assessment of the outcome have been influenced by knowledge of intervention received?
rct_d4_4
|
The document states the study was 'double blind' and that 'scholars involved in randomization, distribution and administration of study articles were independent from the investigators.' However, it does not explicitly describe any specific procedures to ensure blinding of outcome assessors (e.g., whether assessors were separate from those administering interventions, or whether any blinding of outcome assessment was maintained). For subjective outcomes (e.g., Hamilton Anxiety Rating Scale, sleep diary), knowledge of intervention could bias assessment, and the document provides no explicit evidence that outcome assessors were blinded. Therefore, there is insufficient evidence to rule out bias in outcome assessment.
