To assess the short-term efficacy and toxicity of antimalarials for the treatment of rheumatoid arthritis (RA). We searched the Cochrane Musculoskeletal Group's trials register, the Cochrane Controlled Trials Register, Medline and Embase up to and including August 2000. We also carried out a handsearch of the reference lists of the trials retrieved from the electronic search. All randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing antimalarials against placebo in patients with RA DATA COLLECTION AND ANALYSIS: Data abstraction was carried out independently by two reviewers. The same two reviewers using a validated checklist (Jadad 1996) assessed the methodological quality of the RCTs and CCTs. Rheumatoid arthritis outcome measures were extracted from the publications for the 6-month endpoint. The pooled analysis was performed using standardized mean differences for joint counts, pain and global assessments. Weighted mean differences were used for erythrocyte sedimentation rate (ESR). Toxicity was evaluated with pooled odds ratios for withdrawals. A chi-square test was used to assess heterogeneity among trials. Fixed effects models were used throughout. We found four trials, with 300 patients randomized to hydrochloroquine and 292 to placebo. Only trials evaluating hydroxychloroquine could be pooled in the analysis. A statistically significant benefit was observed when hydroxychloroquine was compared to placebo. The standardized mean differences for the various outcome measures ranged from -0.33 to -0.52, and were statistically significant. Statistically significant differences were also observed for ESR. Overall withdrawals and withdrawals due to lack of efficacy were significantly more frequent in the placebo group. No differences were observed in withdrawals due to toxicity. Hydroxychloroquine appears to be efficacious for the treatment of RA. Its overall effect appears to be moderate, but its low toxicity profile should be considered when treating patients with RA.

Attention Score in Context

This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 November 2021.
All research outputs
of 21,108,726 outputs
Outputs from Cochrane database of systematic reviews
of 12,078 outputs
Outputs of similar age
of 188,696 outputs
Outputs of similar age from Cochrane database of systematic reviews
of 104 outputs
Altmetric has tracked 21,108,726 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 12,078 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 28.7. This one is in the 38th percentile – i.e., 38% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 188,696 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
We're also able to compare this research output to 104 others from the same source and published within six weeks on either side of this one. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
