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

Coronavirus disease 2019 (COVID-19) has been reported to induce persistent symptoms even after an acute phase. However, the pathophysiology and treatment of this condition have been unclear. We report two patients who recovered from COVID-19, but presented persistent respiratory symptoms. Their respiratory conditions deteriorated, and computed tomography showed remaining ground glass opacities and consolidations. The pathological findings of transbronchial lung biopsy corresponded to organizing pneumonia. We diagnosed them with secondary organizing pneumonia after COVID-19. Subsequently, we administered systemic corticosteroids. Their symptoms, oxygenations, radiologic findings, and pulmonary functions rapidly improved after the treatment of corticosteroids. The two cases showed that secondary organizing pneumonia may be a cause of persistent respiratory failure after COVID-19. In this condition, corticosteroids may be effective.
