Fig. 2. (A) Change in Visual Analogue Scale (VAS) presented as mean±standard deviation. (B) Change in calculated EuroQoL 5D (EQ-5D) presented as median and interquartile range (IQR). (C) Change in Oswestry Disability Index (ODI), presented as median and IQR. Comparison between aceclofenac controlled release (CR; 200 mg once daily) and conventional aceclofenac (100 mg twice daily) showed there was significant reduction of pain and ODI score, and increase in EQ-5D for each group at 2 weeks, however, there was no difference between groups pre- and post-treatment for VAS, ODI, and EQ-5D. ^*p<0.05, ^†Non-significant.
