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

Aspiration-related pneumonia can progress to empyema and massive hydropneumothorax, potentially fatal complications not frequently documented in the literature. Patients with structural lung disease and poor dentition can be particularly vulnerable to severe polymicrobial infections arising from seemingly minor aspiration events. We report the case of a man in his early 70s with chronic bronchiectasis, heart failure with reduced ejection fraction, coronary artery disease status post coronary artery bypass grafting, type 2 diabetes mellitus, chronic kidney disease, and poor dentition who presented with progressive dyspnea and acute hypoxemic respiratory failure. Imaging demonstrated a massive right-sided hydropneumothorax with complete right lung collapse and mediastinal shift. Pleural fluid cultures grew
