HGS, handgrip strength; hsCRP, high-sensitivity C-reactive protein. Data were expressed as mean ± standard deviation, median (including the lowest and highest quartile), or percentage. Student’s t, Mann–Whitney, chi-squared, or Fisher’s tests were performed. Values lower than 0.05 were considered statistically significant
