Association between body mass index and survival outcomes for in-hospital cardiac arrest.
Article in Resuscitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundBody mass index (BMI), a key clinical marker, may influence outcomes after in-hospital cardiac arrest (IHCA), but its association with neurologically favorable survival remains unclear.
methodsWithin Get With The Guidelines®-Resuscitation, we analyzed 56,411 IHCA patients with BMI data during 2006-2012. BMI was classified as underweight (<18.5 kg/m
resultsAmong 10,219 patients with a shockable rhythm, 3014 (29.4%) had favorable neurological survival, and 3,964 (38.7%) survived to discharge. After adjustment, compared with normal BMI patients, underweight patients had lower favorable neurological survival (OR 0.64 [95%CI: 0.49-0.84]), while overweight (OR 1.17 [1.04-1.33]) and obese (OR 1.16 [1.00-1.34]) patients had higher rates of favorable neurological survival; no difference was seen for very obese patients (OR 1.06 [0.91-1.24]). A similar pattern was observed for survival to discharge. Among 46,192 patients with a non-shockable arrest rhythm, 4844 (10.4%) had favorable neurological survival, and 7,331 (15.8%) survived to discharge. After adjustment, all BMI groups had similar rates of favorable neurological survival and survival to discharge, except for underweight patients (OR 0.76 [0.66-0.89] and 0.85 [0.75-0.95], respectively).
conclusionsFor patients with IHCA, underweight patients had lower rates of survival and favorable neurological survival, regardless of initial cardiac arrest rhythm. In contrast, overweight and obese patients had better outcomes only when the initial rhythm was shockable.
