Statistically significant values (p < 0.05) are given in bold
An independent samples t test was used to compare differences in continuous variables between matched SSRI-users and non-users. Proportions for dichotomous variables were compared by chi-square test or Fisher’s exact test for small sample sizes. High alcohol intake was defined as more than three standard drinks per day
SSRI selective serotonin reuptake inhibitors, MCS mental health component scale, PCS physical health component scale. Previous fracture fracture after the age of 50
