Rationale and Design of the COVID-19 Outpatient Prevention Evaluation (COPE - Coalition V) Randomized Clinical Trial: Hydroxychloroquine vs. Placebo in Non-Hospitalized Patients.
Article in Arquivos brasileiros de cardiologia, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04466540 (Pragmatic, Double-blind, Placebo-controlled Randomized Clinical Trial, Evaluating Hydroxychloroquine for Prevention of Hospitalization and Respiratory Complications in Non-hospitalized Patients With Confirmed or Probable COVID-19), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
backgroundDespite the need for targeting specific therapeutic options for coronavirus disease 2019 (COVID-19), there has been no evidence of effectiveness of any specific treatment for the outpatient clinical setting. There are few randomized studies evaluating hydroxychloroquine (HCQ) in non-hospitalized patients. These studies indicate no benefit from the use of HCQ, but they assessed different primary outcomes and presented important biases for outcome evaluation.
objectiveTo evaluate if HCQ may prevent hospitalization due to COVID-19 compared to a matching placebo.
methodsThe COVID-19 Outpatient Prevention Evaluation (COPE) study is a pragmatic, randomized, double-blind, placebo-controlled clinical trial evaluating the use of HCQ (800 mg on day 1 and 400 mg from day 2 to day 7) or matching placebo for the prevention of hospitalization due to COVID-19 in early non-hospitalized confirmed or suspected cases. Inclusion criteria are adults (≥ 18 years) seeking medical care with mild symptoms of COVID-19, with randomization ≤ 7 days after symptom onset, without indication of hospitalization at study screening, and with at least one risk factor for complication (> 65 years; hypertension; diabetes mellitus; asthma; chronic obstructive pulmonary disease or other chronic lung diseases; smoking; immunosuppression; or obesity). All hypothesis tests will be two-sided. A p-value < 0.05 will be considered statistically significant in all analyses. Clinicaltrials.gov: NCT04466540.
resultsClinical outcomes will be centrally adjudicated by an independent clinical event committee blinded to the assigned treatment groups. The primary efficacy endpoint will be assessed following the intention-to-treat principle.
conclusionThis study has the potential to reliably answer the scientific question of HCQ use in outpatients with COVID-19. To our knowledge, this is the largest trial evaluating HCQ in non-hospitalized individuals with COVID-19.
