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.

Abstract

backgroundMonitoring end-tidal carbon dioxide (EtCO

methodsA single-centre, observational, exploratory feasibility study conducted in Region Uppsala between December 2024 and January 2025. First 20 healthy adult volunteers were transported approximately 10 min by ambulance, having EtCO

resultsA total of 20 volunteers and 29 patients were included in the final analysis. The comparison between the mainstream and reference capnograph showed that median EtCO
