INS and diabetes mellitus: A statistically significant increased risk of hospitalization was observed for both women and men exposed to antihemorrhagics, antianaemic and perfusion preparations (ROR 1.32, 95% CI 1.14–1.52 and 1.33, 1.13–1.56, respectively); sedative or hypnotic agents (ROR 1.11, 1.01–1.21 and 1.15, 1.02–1.31), particularly benzodiazepines; antipsychotics (ROR 1.57, 1.38–1.79 and 1.44, 1.22–1.68); antiepileptics (ROR 1.23, 1.10–1.39 and 1.21, 1.05–1.38); diuretics (ROR 1.25, 1.15–1.36 and 1.16, 1.06–1.26) and, for diabetes agents, insulin (ROR 1.32, 1.12–1.55 and 1.19, 1.01–1.41) (Table 2).
