Grip strength variability independent of the mean

Grip strength variability independent of the mean is associated with successful aging in humans (OR 0.648, 95% CI 0.417-0.962, P = 0.042).

“Variability Independent of the Mean (VIM) was significantly negatively associated with successful aging - after full covariate adjustment, each 1-unit increase was associated with a 35.2% lower probability of achieving successful aging (OR = 0.648, 95% CI: 0.417-0.962, P = 0.042)”
