Number of publications by year: (A) single-factor NHANES analyses identified in this review (B) total publications by year identified by a PubMed search for “biobank”.
Both data series show publication counts for 2024 to 9 October only. The data underlying these figures are additionally reported in S1 Data Table D.
Fig 4.
Network analysis of health conditions and their associations with predictor variables from NHANES published research focusing on single-factor relationships.
Outer shell nodes are predictor variables, inner shell nodes are health conditions with four or more associated predictor variables and edges represent a paper in this systematic review describing a statistically significant single-factor relationship. Diameters of nodes are proportional to the number of papers. Only nodes with more than four edges are labeled. The data underlying these figures are taken from the pivot tables presented in S1 Data Tables B and C.
