Figure 1. Hand grip strength according to serum hsCRP quartiles in men (A) and women (B). Delta (Δ) indicates a change in hand grip strength from the lowest quartile (Q1). Values are presented as the estimated mean with 95% confidence intervals after adjustment for confounding factors using analysis of covariance (ANCOVA). Confounding variables include age, body mass index, smoking and drinking habits, resistance exercise, fasting plasma glucose, serum total cholesterol, and systolic blood pressure. *Statistically significantly different from the Q1 by ANCOVA. hsCRP, high sensitivity C-reactive protein.
