Studies comparing hyaluronan (HA)–based viscosupplements for osteoarthritis
hyalarthritis.Rd
A dataset from of trials for pain reduction for patients with osteoarthritis treated with HA-based viscosupplements(Jansen et al. 2015) . Data are reported in each study arm as mean change from baseline to follow-up on a visual analogue scale (0-100). The dataset includes 16 Randomised-Controlled Trials (RCTs), comparing 6 treatments and placebo.
Format
