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

Combined pulmonary fibrosis and emphysema (CPFE) is characterized by emphysematous lesions in the upper lung field and pulmonary fibrosis in the lower lung field and is often associated with pulmonary hypertension and severe exercise-induced hypoxemia (EIH). We herein report a 62-year-old man with CPFE who presented with severe EIH despite relatively preserved lung volumes. Cardiopulmonary exercise testing suggested exercise-induced right-to-left shunt (EIS) through a patent foramen ovale (PFO). EIS was attributed to exercise-induced pulmonary hypertension. In this case report, we highlight the possibility of EIS using PFO for CPFE. We also discuss potential treatments including pharmaceutical interventions and PFO closures.
