LASI is India’s first ageing study and the world’s largest in terms of sample size, and will provide comprehensive longitudinal data for designing policies and programmes targeted toward the overall well-being of the older population. Additionally, as part of the recommended ethics protocols, participants received a copy of the consent forms, biomarker results report card and referral letters to the public health facility if their health measurements were found to be outside the normal range. For India, the overall household response rate was 95.8% and the overall individual response rate was 87.3%.

How this study scored 71/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 41 of the 58 points we could judge it on, which is 71 out of 100.
