The relationship between a lower body mass index and reintubation among critically ill patients: a multicenter retrospective cohort study.
Article in Journal of anesthesia, analgesia and critical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundUnderweight critical care patients are at an increased risk of in-hospital mortality. This vulnerability is attributed to the lack of physiological reserve, which may increase the risk of reintubation in these patients. However, the association between underweight and reintubation remains unclear. We aimed to assess the association between a lower body mass index (BMI) and the risk of reintubation in mechanically ventilated patients.
methodsWe performed a retrospective cohort study using data from the Japanese Intensive care PAtient Database (JIPAD). We included adult patients who received mechanical ventilation for at least 24 h from intensive care unit (ICU) admission between 2018 and 2023. The primary outcome was reintubation, which was defined as the reimplementation of mechanical ventilation within 72 h after extubation. BMI was categorized into five groups: underweight (< 18.5 kg/m
resultsOf the 41,016 eligible patients from 131 ICUs, the mean BMI was 23.4 kg/m
conclusionA lower BMI was associated with an increased risk of reintubation. This relationship remained consistent in the age-stratified subgroup analysis. The present results indicate that a lower BMI needs to be considered an important factor when assessing an underweight patient's risk of reintubation.
