The original version of this article unfortunately contained a mistake in Table 2. The data under column head “Left handgrip strength (n = 336)” was erroneously omitted during the production process. The corrected Table 2 is given below.
Table 2.
Results from multiple multilevel regression analyses with FCE test performances as dependent variables are given; unstandardized regression coefficients and their standard errors (b(SE)), and model’s deviance (− 2 * LogLikelihood) by the addition of random and fixed effects are shown
