62 participants (n1=31 / n2= 31)
|Characteristics of participants|
Mean age : 55.4
Severity : Mild: n=0 / Moderate: n=0/ Severe: n=45 Critical: n=15
|In the register|
Complete remission of clinical signs of disease (7 days), negative result for COVID-19 RT-PCR test and normal scan (14 days).
|In the report|
Improvement in the levels of cytokine storm indices
|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
|General comment||In addition to the published article, the retrospective trial registry was used in data extraction and assessment of the risk of bias. The study achieved the estimated sample size. There may be some changes from the trial registration in the intervention treatment. Of note, the trial was described as single-blind in the report; however, participants, investigators, outcome assessor, data analyzer would be masked according to the registry. The registry primary outcome does not reflect the reported primary outcome. None of the primary outcomes in the registry are reported in the article (complete remission, negative RT-PCR, normal CT scan), while several outcomes not in the registry are reported (length of hospitalization WHO 8-point ordinal scale severities, adjusted analyses of laboratory outcomes and survival).|
