The De Ritis ratio mediates the association between creatinine-to-body weight ratio and normoglycemic conversion in Chinese health examinees.

To assess the associations between the creatinine-to-body weight (Cre/BW) ratio and reversion to normoglycemia mediated by the aspartate aminotransferase-to-alanine aminotransferase (De Ritis) ratio. This retrospective cohort study included 24,884 prediabetic participants from health check-ups in 32 regions across 11 Chinese cities. We employed multivariable Cox regression to assess time-to-event outcomes, smooth curve fitting for trend analysis, and inflection point analysis to determine critical thresholds.
