Characteristics associated with hospitalisation for COVID-19 in people with rheumatic disease: data from the COVID-19 Global Rheumatology Alliance physician-reported registry
Analysis of rheumatic disease patients showing no significant association between antimalarial therapy and hospitalisation, OR=0.94 [0.57-1.57],
p=0.82 after adjustments.

risk of hospitalization, 3.3% lower, RR 0.97, p = 0.82, treatment 58 of 130 (44.6%), control 219 of 470 (46.6%), odds ratio converted to relative risk.
This study is excluded in meta analysis: not fully adjusting for the baseline risk differences within systemic autoimmune patients.
Effect extraction follows
pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
