Table 1 Demographic variables and their relationships with grip strength. Note that computerized Go/No-Go Accuracy is not included as the data were not normally distributed. This variable was treated as a dichotomous outcome in the multivariate analyses

From: The relationship between clinical measures of cognitive function and grip strength in healthy older adults
