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

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, potentially curable form of pulmonary hypertension, with limited data in pregnancy. We describe a 37-year-old woman with progressive dyspnea, back pain, and cough, whose evaluation revealed severe right ventricular enlargement, high pulmonary pressures, and extensive V/Q mismatches, confirming CTEPH. She underwent successful pulmonary thromboendarterectomy with marked hemodynamic recovery. An unrecognized early pregnancy, later confirmed after spontaneous miscarriage at 14 weeks, complicated the course. This case underscores the diagnostic challenges of CTEPH in women of reproductive age and highlights the impact of pregnancy-related hemodynamic stress on disease presentation.
