Statistical analysis
Statistical analyses were performed with the Statistical Package of
Social Sciences version 21.0 (SPSS, Chicago, IL). The SPSS normality
test was used to determine whether the data were normally distributed or
not. Because the skewness and kurtosis values of our data were
distributed within ±1.5 range10 it was decided that the data were
distributed normally. Data were presented as means and standard
deviation and numbers (n) and percent (%). One-Way ANOVA test including
post-hoc analysis and χ2 test were performed for comparison of variables
according to nocturia severity. P<0.05 was considered
statistically significant.
