Prehospital Normoventilation in Critically Ill Anaesthetised Patients Cannot Be Reliably Monitored by Capnography-A Retrospective Observational Study.
Observational study in Acta anaesthesiologica Scandinavica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEnd-tidal carbon dioxide capnography (EtCO
methodsWe carried out a retrospective study of all anaesthetised and intubated patients with a measured PaCO
resultsIn Bland-Altman analysis, the overall bias was 1.7 kPa (standard deviation = 1.6) with limits of agreement of -1.4 to 4.8 kPa. Out of 670, the PaCO
conclusionsOur results show that for critically ill patients intubated in the prehospital setting, capnography is not accurate in guiding ventilation. EDITORIAL COMMENT: Capnography may be used to assess ventilation effect in intubated patients. In an intubated helicopter ambulance mixed-diagnosis cohort end-tidal carbon dioxide levers were assessed, compared to pCO
