An observational study of end-tidal carbon dioxide trends in general anesthesia.
Observational study in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05550181 (Associations of Intraoperative Hypocapnia With Patient Demographics, Ventilation Characteristics and Outcomes--Statistical Analysis Plan for an Individual Patient Data Analysis of PROVHILO and PROBESE), which is not on this map. Cited by 8 papers.
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.
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
purposeDespite growing evidence supporting the potential benefits of higher end-tidal carbon dioxide (ETCO
methodsThis retrospective, observational, multicentre study included 317,445 adult patients who received general anesthesia for non-cardiothoracic procedures between January 2008 and September 2016. The primary outcome was a time-weighted average area-under-the-curve (TWA-AUC) for four ETCO
resultsBoth TWA-AUC and median ETCO
conclusionsBetween 2008 and 2016, intraoperative ETCO
