Fig. 4From: Could an optimally fitted categorization of difference between multi-disease score and multi-symptom score be a practical indicator aiding in improving the cost-effectiveness of healthcare delivery for older adults in developing countries?Distribution consistency of the subpopulations stratified between by health decline score and by multi-disease or multi-symptom pattern. Subpopulations harboring different age-dependent health decline and harboring different aging-associated multi-disease patten or multi-symptom patten were highly consistent, which was shown using a percentage-dependent gradient correlation. It meant aging-increased multimorbidity (depicted by color palette) was distributed in parallel to the increased health decline (depicted by grey palette), and vice versaBack to article page
