[…] All statistical analyses were conducted in R version 3.2.4 with the packages ‘epitools’, ‘qcc’ and ‘ggplot2’. Confidence limits for the IR and IRR were based on the Poisson distribution, using a mid-P exact test []. We used Fisher’s exact test for count data to compare proportions. We modelled the incidence rates of schizophrenia with a generalized linear model using a log link and a quasi-poisson family (i.e. estimating the dispersion parameter from the data to adjust for over-dispersion).
