Cardiac index is associated with oxygenation in COVID-19 acute respiratory distress syndrome.
Article in Pulmonary circulation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Eleven participants with COVID-19 acute respiratory distress syndrome requiring mechanical ventilation underwent pulmonary artery catheterization for clinical indications. Clinical interventions or events concurrent with hemodynamic were recorded. Increased cardiac index was associated with worse hypoxemia. Modulation of cardiac index may improve hypoxemia in patients with COVID-19 acute respiratory distress syndrome.
