Fig. 2: The association of inflammation-related markers with area-level deprivation and frailty.

A The most important 20 proteins associated with socially deprived frail vs non socially deprived non frail conditions as identified using SHapley Additive exPlanation (SHAP) values from the Random Forest modelling. B The association of inflammatory markers with frailty index and IMD. Beta coefficients were calculated using linear mixed models adjusting for age and BMI with batch effects and family relatedness as random effects. Beta [95%CI] is reported for the association of frailty index and IMD with inflammatory proteins in the overall population (n = 2144).
