S1: How representative was the exposed cohort?
cs_s1
|
The study describes sampling from 12 coastal sites and two aquaculture systems but provides no information about how these sites were selected or whether they represent a defined population. While locations are specified (Singapore coastal waters), there is no explicit description of the derivation process or representativeness of the sampling sites relative to the broader community of exposed environments. The absence of methodological details about site selection meets NOS criteria for 'no description of derivation' (option d).

S2: How was the non-exposed cohort selected?
cs_s2
|
The study explicitly states that both exposed (aquaculture farms) and non-exposed cohorts (surrounding marine sites) were sampled from the same geographical area (Singapore's coastal waters). The methodology describes all sampling locations as being part of a unified coastal monitoring program within the same tropical coastal region, meeting NOS criteria for same community/source population.

S4: Was the outcome of interest not present at the start of the study?
cs_s4
|
The study describes a monitoring program but provides no explicit evidence that antimicrobial resistance determinants (ARB, ARGs, antibiotics) were absent at baseline. While samples were collected over a 1-year period, there is: 1) No statement about baseline outcome status 2) No exclusion of sites with pre-existing AMR 3) No prospective cohort design with incident case tracking

C1: Were the cohorts comparable on the basis of design or analysis, controlling for confounders?
cs_c1
|
No explicit documentation of controlling for confounders in study design or analysis. While environmental variables and seasonal variations were analyzed as factors influencing AMR distribution, there is no stated adjustment for demographic or biological confounders (age, sex, etc.). The cluster analysis categorized sites by location/season but did not demonstrate cohort comparability through confounder control.

O1: How was the outcome assessed?
cs_o1
|
The document describes laboratory methods for outcome assessment (PCR and sequencing) but provides no evidence of independent blind assessment or record linkage. While antibiotic resistance genes/bacteria were quantified through technical processes, there is no explicit mention of assessor blinding, independence, or use of official registries. The methods described fall under standard laboratory analysis without documented quality control measures required for NOS star allocation.

|
O2: Was the follow-up long enough for outcomes to occur?
cs_o2
|
The study explicitly states a 1-year monitoring period with monthly sampling, which is explicitly stated as sufficient for observing seasonal variations and AMR dynamics in coastal environments. This duration is appropriate for environmental monitoring studies assessing temporal patterns.
|
star awarded | |
|
O3: Was the follow-up adequate (i.e., completeness)?
cs_o3
|
The document contains no explicit statements about follow-up completeness or loss to follow-up rates. While the methodology describes sample collection procedures (146 water samples collected monthly from 12 sites over 1 year, plus quarterly sediment/fish samples), there is no: 1) Numerical accounting of all collected vs. analyzed samples 2) Mention of sample attrition/loss 3) Description of characteristics of any lost samples 4) Discussion of potential bias from incomplete follow-up. The absence of these key elements prevents assessment of follow-up adequacy.
