The meta‐analysis showed that a per 1 mg/L increase in CRP was significantly associated with a higher risk of sarcopenia overall (crude OR = 1.09; 95% CI: 1.00–1.19; I2 = 29.7%; p = 0.034; adjusted OR = 0.66; 95% CI: 0.10–4.16; I2 = 95.8%; p = 0.655; Figure 5). This evidence concerns the gene CRP and sarcopenia.
