From: Ethnic inequalities in time to diagnosis of cancer: a systematic review
CASP question | Was the cohort representative of a defined population? | Was everybody included | Was the exposure accurately measured to minimize bias? | Was the outcome precisely measured to minimize bias? | Have the authors identified and adjusted for all key confounding factors? | How precise are the results? | Overall quality |
---|---|---|---|---|---|---|---|
Adapted question | Unchanged | Were all eligible cancer patients studied? | Was ethnicity defined according to contemporary groupings? | Was diagnostic intervals measured to Olsen and colleagues framework? | Unchanged. Key confounders include: age, gender, SES, co-morbidity, healthcare system, family history of cancer and tumour growth rates | Have they presented estimates of association along with the confidence intervals? Are the confidence intervals narrow? | Unchanged |
