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
Kaizu R, Maruyama H, Tanaka N, Takahashi H, Kigawa H. A Case of Platypnea-Orthodeoxia Syndrome Following COVID-19 Pneumonia Treated in a Convalescent Rehabilitation Ward. Jpn J Compr Rehabil Sci 2026; 17: 46-52. Platypnea-orthodeoxia syndrome (POS), characterized by worsening hypoxemia associated with postural changes, has been reported as a complication following pneumonia due to coronavirus disease 2019 (COVID-19). In most cases, POS improves during the acute phase. We report a case in which POS was diagnosed in a convalescent rehabilitation ward, with symptoms persisting for more than 100 days, ultimately enabling discharge to home. The patient was a 76-year-old man who, despite receiving acute-phase treatment for COVID-19 pneumonia, continued to exhibit marked oxygen desaturation and dyspnea in the sitting and standing positions, resulting in difficulty with mobilization. Following admission to the convalescent rehabilitation ward, decreases in SpO
