Effect of Tocilizumab on "Ventilator Free Days" Composite Outcome in SARS-CoV-2 Patients: A Retrospective Competing Risk Analysis.
Article in Romanian journal of anaesthesia and intensive care, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: SARS-CoV-2 infection demonstrates a wide range of severity. More severe cases demonstrate a cytokine storm with elevated serum interleukin-6, hence IL-6 receptor antibody tocilizumab was tried for the management of severe cases. Aims: Effect of tocilizumab on ventilator-free days among critically ill SARS-CoV-2 patients. Method: Retrospective propensity score matching study, comparing mechanically ventilated patients who received tocilizumab to a control group. Results: 29 patients in the intervention group were compared to 29 controls. Matched groups were similar. Ventilator-free days were more numerous in the intervention group (SHR 2.7, 95% CI: 1.2 - 6.3; p = 0.02), ICU mortality rate was not different (37.9% versus 62%, p = 0.1), actual ventilator-free periods were significantly longer in tocilizumab group (mean difference 4.7 days; p = 0.02). Sensitivity analysis showed a significantly lower hazard ratio of death in tocilizumab group (HR 0.49, 95% CI: 0.25 - 0.97; p = 0.04). There was no difference in positive cultures among groups (55.2% in tocilizumab group versus 34.5% in the control; p = 0.1). Conclusion: Tocilizumab may improve the composite outcome of ventilator-free days at day 28 among mechanically ventilated SARS-CoV-2 patients; it is associated with significantly longer actual ventilator-free periods, and insignificantly lower mortality and higher superinfection.
