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

Rapid and accurate measurement of carboxyhemoglobin (COHb) is essential in managing acute carbon monoxide poisoning (ACOP). Non-invasive pulse CO-oximetry (SpCO) offers a convenient alternative to arterial blood gas analysis (ABGA), but its clinical accuracy and reliability in low COHb severity remain uncertain. This study evaluated the agreement and predictive performance of SpCO compared to arterial COHb in ACOP patients. In this prospective observational study, 81 ACOP patients underwent paired measurements of SpCO and arterial COHb. Patients were categorized into three groups based on COHb severity: low (< 10%), moderate (10-20%), and high (> 20%). Agreement was assessed using Deming and Passing-Bablok regression, Lin's concordance correlation coefficient (CCC), Bland-Altman analysis, and accuracy metrics (R
