Contribution of malaria and sickle cell disease to anaemia among children aged 6–59 months in Nigeria: a cross-sectional study using data from the 2018 Demographic and Health Survey is a dataset published in BMJ Open (2022). On theSindex it has a DataRank of 0.361, placing it in the top 49.2% of the data-sharing corpus. It has been cited 4 times, with 4 citing works in its 1-hop citation network. Its calibrated FAIR score is 15/100.
Ranks in the top 49% for downstream scientific impact
DataRank reads this dataset's downstream impact straight off the citation graph — no black box, no proprietary weighting. How is this computed?
FAIR checklist signals are shown for context only and do not affect DataRank scoring.
Full FAIR picture · advisory
The headline score is computed from the scored criteria — the fact-shaped checks (a repository, an accession, a licence) that two independent models agree on. The advisory criteria below are real FAIR guidance but rest on judgment calls that models read differently, so they inform without moving the number.

“We obtained data from Nigeria’s 2018 DHS. A sample of 42 000 households were selected for participation in the survey. DHS interviews were conducted from 14 August to 29 December 2018. One-third of households (14 000) were randomly selected for biomarker evaluation. Children 6–59 months old who were de facto residents of these households (ie, slept in household last night) were eligible for biomarker testing (11 536 eligible children). ... In total, 11 142 children (96.6% of eligible children) with all three biomarker measurements were included in our analyses.”— not found in the paper; verdict downgraded
