Figure 1: Comparison of trend of variables changes between study groups. (a) Pain domain, (b) urinary score, (c) quality of life, and (d) total NIH-CPSI score. Differences in the scores of pain domain ( value = 0.001), urinary score (-value = 0.039), quality of life (-value < 0.0001), and total NIH-CPSI score (-value < 0.0001), between cases and controls were statistically significant. -axis: time points. -axis: mean of scores. -values calculated by repeated measurements of ANOVA.
