Case Volume of Targeted Temperature Management and Neurological Outcomes in Comatose Out-of-Hospital Cardiac Arrest Survivors: Nationwide Population-Based Study.
Article in Korean circulation journal, 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
BACKGROUND AND
objectivesCase volume and improved survival have been reported in several critical illnesses; however, the impact of case volume of targeted temperature management (TTM) on neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients remains unclear. This study aimed to determine whether TTM case volume is associated with neurologically intact survival in comatose OHCA patients.
methodsThis observational study included consecutive adult (≥18 years) OHCA survivors with TTM using data from the Nationwide OHCA Registry in South Korea between 2016 and 2021. TTM case volume was evaluated in 2 ways. First, TTM volume was included as a continuous variable in a restricted cubic spline analysis. Second, TTM case volume was categorized into tertiles (high: ≥17.0 cases/year, medium: 12.0-16.9, and low-volume: <12.0 cases/year), and multivariable logistic regression analysis using generalized estimating equations was performed on good neurologic outcomes (cerebral performance category 1-2) based on the low-volume center.
resultsOverall, 4,018 OHCA survivors treated with TTM were included. In spline analyses, the overall association was significant; non-linearity was not detected in the primary 3-knot model but was observed in sensitivity models with alternative knot placements (4-knot: p=0.005; p for non-linearity=0.045). Although coronary angiography was lower in the high-volume center, multivariable analysis showed that a high-volume TTM center was associated with a good neurological outcome (adjusted odds ratio, 1.45; 95% confidence interval, 1.16-1.81; p=0.001).
conclusionsHigher TTM case volume was associated with better neurological outcome in comatose OHCA survivors and may reflect greater overall post-arrest care capability.
