Factors associated with survival after pediatric in-hospital cardiac arrest: A national database analysis 2015-2022.
Article in PloS one, 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
backgroundPediatric in-hospital cardiac arrest (IHCA) is frequently fatal, and evidence from middle-income settings needed to guide quality improvement is sparse. We used nationwide Thai data to quantify incidence and mortality trends, describe long-term outcomes, and identify associated factors for post-discharge death after pediatric IHCA.
methodsWe performed a retrospective cohort study using the Thai National Health Security Office database encompassing all hospitalizations under the universal health-coverage scheme from 1 January 2015-31 December 2022. Children <18 years with IHCA were identified by ICD-10-TM codes I46.0/I46.1/I46.9 plus at least one resuscitation procedure code (ICD-9-CM 99.60/99.62/99.63). All-cause mortality through 31 December 2023 was obtained via linkage to the national civil registry.
resultsAmong 13.2 million pediatric admissions, 20,590 IHCAs were recorded (incidence 1.57/1,000). Incidence declined from 1.8/1,000 in 2015-2016 to 1.2/1,000 in 2022. In-hospital mortality was 62.7% (12,905/20,590). Of 7,253 survivors with follow-up (median 67 months), 2,149 (29.6%) died post-discharge. Multivariable analysis identified metabolic acidosis (adjusted hazard ratio [aHR] 1.50; 95% confidence interval [CI] 1.32-1.71) and hypoglycemia (aHR 1.54; 95% CI 1.25-1.89) as significant associated diagnoses with long-term mortality. Furthermore, diagnoses consistent with severe organ dysfunction, including disseminated intravascular coagulation (aHR 1.51; 95% CI 1.24-1.85), acute liver failure (aHR 1.42; 95% CI 1.10-1.84), and anoxic brain injury (aHR 1.23; 95% CI 1.05-1.44), were also significantly correlated with increased mortality; however, the timing of these diagnoses relative to the cardiac arrest could not be determined.
conclusionsPediatric IHCA in Thailand remains highly fatal despite recent declines in incidence and in-hospital mortality. During a median follow-up of 67 months, nearly one-third of survivors died after discharge, underscoring the substantial long-term mortality burden. Metabolic derangements and organ dysfunction were strongly associated with post-discharge mortality, highlighting the need for targeted strategies to improve both survival and long-term outcomes.
