Multilevel random effects logistic regression with short- and long-term sickness absence as outcome variables. Employee-quarters nested within employees, employees nested within units and units nested within departments
Significance: the level of statistical significance was set to p < .01. In the table, ** = p < .01; *** = p < .001
Abbreviations: SA sickness absence, OR odds ratio, CI 95% confidence intervals, ns not significant

a Control variables not included
b Control variables included
c The results are calculated with the restriction “iterate (10)” to make converging possible with three random intercepts. The results are similar to those with two random intercepts (employee and work-unit) and without the iterate restriction
