1 · What the graph read from it

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.

2 · The registry

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Tocilizumab has been repurposed against the 'cytokine storm' in the setting of coronavirus disease 2019 (COVID-19). Our aim was to evaluate the efficacy of tocilizumab in the management of hospitalized COVID-19 patients. We searched MEDLINE, CENTRAL and medRxiv for studies of tocilizumab in hospitalized COVID-19 patients. Primary objective was the effectiveness of tocilizumab on mortality. Secondary objectives included the need for invasive mechanical ventilation (IMV), composite endpoints of mortality or IMV and intensive care unit (ICU) admission or IMV, length of hospitalization and differences in mortality in subgroups (ICU and non-ICU patients and patients receiving or not receiving concomitant corticosteroids). We included 52 studies (nine randomized controlled trials [RCTs] and 43 observational) with a total of 27,004 patients. In both RCTs and observational studies, the use of tocilizumab was associated with a reduction in mortality; 11% in RCTs (risk ratio [RR] 0.89, 95% CI 0.82 to 0.96) and 31% in observational studies (RR 0.69, 95% CI 0.58 to 0.83). The need for IMV was reduced by 19% in RCTs (RR 0.81, 95% CI 0.71 to 0.93), while no significant reduction was observed in observational studies. Both RCTs and observational studies showed a benefit from tocilizumab on the composite endpoint of mortality or IMV. Tocilizumab improved mortality both in ICU and non-ICU patients. Reduction in mortality was evident in observational studies regardless of the use of systemic corticosteroids, while that was not the case in the RCTs. Tocilizumab was associated with lower mortality and other clinically relevant outcomes in hospitalized patients with moderate-to-critical COVID-19.
