Table 3 Unadjusted logistic regression analyses between the continuous GMSI scores and the dichotomized workability score (WAS)

From: Supportive and demanding managerial circumstances and associations with excellent workability: a cross-sectional study of Swedish school principals

Independent variables Total study sample (n = 2119) Women (n = 1724) Men (n = 491)
