°: Turnover and up-down sizing expressed as rate per 100 FTEs. * Age mix: younger vs. older age prevalence ratio, where younger age is defined as age below the median age, specific for each year. ** Skill mix: low vs. high experience level prevalence ratio, where low experience is measured from professional qualification level. ^: Prevalence ratios and 95% confidence intervals (in brackets), with day shift as reference category, estimated from log-binomial models.
