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

This single-centre retrospective cohort study demonstrates that arterial blood gas (ABG) parameters independently stratify ICU admission risk in acute carbon monoxide poisoning (ACOP) beyond carboxyhemoglobin (COHb). Among 124 ACOP patients, the acidosis group (pH<7.35) had a higher ICU admission rate [44.8%, 95% Confidence Interval (CI): 26.8%∼63.7%] than the normal pH (17.7%, 95%CI: 10.1%∼27.5%) and alkalemia groups (12.5%, 95%CI: 1.6%∼38.3%, P<0.001), with a median COHb of 33.1%. The acidosis group presented severe metabolic disturbance (median lactate 7.60 mmol/L, GCS 7). Spearman analysis showed arterial lactate was more strongly associated with disease severity markers than COHb. Multivariate logistic regression confirmed GCS score, COHb, arterial lactate, and HCO3 as independent predictors for ICU admission.
