aContinuous variables are shown as mean ± standard deviation (95% confidence interval), categorical variables are shown as number of patients and percentages per group.
b Post hoc analyses revealed a significant difference between ‘no tear’ and ‘major tear’ (P < 0.001) and between ‘minor tear’ and ‘major tear’ (P = 0.002).
c Post hoc analysis revealed a significant difference between ‘no tear’ and ‘major tear’ (P = 0.015).
d Post hoc analyses revealed a significant difference between ‘no tear’ and ‘minor tear’ (P = 0.006), between ‘no tear’ and ‘major tear’ (P < 0.001), and between ‘minor tear’ and ‘major tear’ (P = 0.009).
