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.

  • n Numeric data indicating the number of participants randomised to each arm

  • y Numeric data indicating the mean change from baseline in HbA1c in a study arm

  • se Numeric data indicating the standard error for the mean change from baseline in HbA1c in a study arm
