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 obstructive pulmonary disease (COPD) is a recognized risk factor for poor outcomes in SARS-CoV-2 infection, yet its specific impact on critically ill patients remains unclear. We aimed to compare the clinical and laboratory profiles of ICU SARS-CoV-2 pneumonia patients with or without pre-existing COPD and identify factors associated with mortality among those with COPD. In this retrospective study, adult intensive care unit (ICU) admissions for SARS-CoV-2 pneumonia (n = 1536) were divided into a COPD group (n = 253) and a non-pulmonary-disease (NPD) group (n = 1283). Demographics and clinical characteristics, severity of disease, length of stay, laboratory values, and survival outcomes were compared. COPD patients were older, had higher Acute Physiology and Chronic Health Evaluation score, and had a greater prevalence of comorbidities (
