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

Identifying reliable prognostic markers is crucial for the effective management of chronic obstructive pulmonary disease (COPD). The platelet count has emerged as a potential inflammatory marker associated with clinical outcomes. The aim of this study was to investigate the relationships of the platelet count with all-cause mortality and readmission rates among patients with acute exacerbations of COPD (AECOPD). Patients who were diagnosed with AECOPD between January 2019 and December 2023 at our institution were included. The platelet count was recorded on admission. The primary outcome was all-cause mortality. The secondary outcomes included readmission for AECOPD and a composite endpoint of readmission and mortality. Multivariate Cox proportional hazards models were constructed to examine the associations between the study endpoints and platelet counts categorized as low, normal, and high (< 150, ≥ 150 to < 300, and ≥ 300 × 10
