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.

|
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 mechanism (e.g., central allocation, sequentially numbered sealed envelopes, or other method) to ensure that the allocation sequence was concealed until participants were enrolled and assigned. Without such detail, it is unclear whether those recruiting participants could have foreseen assignments, raising some concerns about potential selection bias.

|
Were participants aware of their assigned intervention during the trial?
rct_d2_1
|
The document explicitly states that the study was 'double-blind' and describes procedures that support participant blinding. The interventions were both capsules of identical dosage (500 mg BD) administered in a parallel group design, and the randomization and administration were handled by independent personnel. There is no mention of any unblinding events or procedures that would compromise blinding. The evidence is sufficient and unambiguous.

|
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 how blinding of carers/personnel was achieved. The only relevant statement is that 'The scholars involved in randomization, distribution and administration of study articles were independent from the investigators.' This implies that those administering the interventions were separate from those who randomized, but it does not confirm that the administrators were unaware of group allocation. Without explicit details on blinding procedures (e.g., identical capsules, placebo control, or masking of personnel), the evidence is insufficient to rule out potential awareness by carers or intervention deliverers.

|
Were there deviations from the intended intervention that arose because of the experimental context?
rct_d2_3
|
The document states that the study was double-blind and that randomization, distribution, and administration of study articles were independent from investigators. However, there is no explicit description of blinding procedures (e.g., whether capsules were identical in appearance, taste, or packaging) or any mention of measures to prevent deviations from intended intervention due to the experimental context (e.g., contamination, co-interventions, or differential attention). The absence of such details raises concerns about potential deviations that could arise because of the trial context.

some concerns | |
|
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.
|
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.

Could missingness in the outcome depend on its true value?

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 and validated tools. There is no evidence of an inappropriate measurement method.
|
low risk | |
|
Could measurement or ascertainment of the outcome have differed between intervention groups?
rct_d4_2
|
The document explicitly states that the study was double-blind and that randomization, distribution, and administration of study articles were independent from investigators. Outcome assessment methods (SBP, DBP, MAP, laboratory tests, Hamilton Anxiety Rating Scale, sleep diary) are described as standardized and applied to both groups. There is no evidence that measurement or ascertainment of outcomes differed between groups.
