  • GRADE Working Group grades of evidence.

  • High quality: further research is very unlikely to change our confidence in the estimate of effect.

  • Low quality: further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

  • Moderate quality: further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.

  • Very low quality: we are very uncertain about the estimate.

  • *The basis for the assumed risk (eg, the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).

  • †After 2 months treatment.

  • ‡Poorly reported paper (see ‘Risk of bias’ table).

  • §Small sample size.

  • CRP, C reactive protein; ESR, erythrocyte sedimentation rate; HAQ, Health Assessment Questionnaire; VAS, visual analogue scale; WMD, weight mean difference.
