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

Purpose: Evidence comparing supraglottic airway with tracheal intubation in out-of-hospital cardiac arrest remains conflicting, and prior meta-analyses covered few randomized trials. We compared these strategies in adults. Methods: PubMed, Embase, and the Cochrane Library were searched from inception to January 2026 for randomized and observational studies comparing the two strategies in adults. Primary outcomes were survival to hospital discharge and return of spontaneous circulation (ROSC); favorable neurological outcome was secondary. Risk of bias was assessed with ROBINS-I and RoB 2, and certainty with GRADE. Risk ratios (RR) with 95% confidence intervals (CI) were pooled using restricted maximum likelihood random-effects models, with heterogeneity ( Results: Thirteen studies (246,659 patients) were included. Survival to hospital discharge did not differ between SGA and TI groups (RR 0.96; 95% CI 0.82-1.12; Conclusion: In out-of-hospital cardiac arrest, survival to hospital discharge did not differ between strategies, whereas SGA placement, compared with TI, was associated with a lower likelihood of ROSC. In an exploratory subgroup analysis of studies reporting neurological outcomes at ≥1 month after OHCA, TI was associated with a higher likelihood of favorable neurological outcome compared with SGA
