Data are shown as mean ± standard error
The SF-36 comprises eight subscales (score of 0–100). Higher scores indicate better quality of life
There were statistically significant differences in two SF-36 subscale scores [physical function and bodily pain (p < 0.05)]. With respect to pain duration, for patients with chronic pain, there were no statistically significant differences in any of the SF-36 subscale scores. For patients with subacute or acute pain, there was a statistically significant difference in one SF-36 subscale score [bodily pain (p < 0.05)]
