Data management and analysis
The collected data were entered in Epi-Data version 3.2 and analyzed based on the intention-to-treat (ITT) principle using Stata/MP version 14.1 (StataCorp LP, College Station, Texas). The normality of data was assessed using Shapiro–Wilk test. Socio-demographic data were analyzed using descriptive analysis. Since the data were normally distributed, the mean and standard deviation (SD) were calculated. Comparisons were made using the Student’s two-sample t-test. The Box and whisker plot was also used to display the PRP and steroid group outcome measures. All values less than 0.05 were considered statistically significant.
