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
Objective: The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) Mortality Categories were developed from large multicenter databases to stratify surgical risk in congenital heart surgery. However, their predictive validity in high-risk subgroups such as neonates and infants of low birth weight, especially in small- to medium-volume centers, remains unclear. Methods: We retrospectively analyzed all congenital cardiac surgeries performed at our center between 2005 and 2025. We assessed 30-day mortality by STAT category in the overall cohort and in prespecified subgroups: neonates (<31 days), non-neonates (≥31 days), and low birth weight (<2.5 kg). We performed correlation analyses and multivariable logistic regression models with interaction terms (STAT × neonate, STAT × low weight). Results: Among 4768 operations, 1257 (26.3%) were in neonates and 191 (4.0%) in patients <2.5 kg. Overall mortality increased progressively with STAT category (1: 1.1%, 2: 3.7%, 3: 5.8%, 4: 12.8%, 5: 26.7%). Neonates exhibited greater mortality across all STAT levels, including categories considered low risk in older children (STAT 1: 9%, STAT 2: 6%). Logistic regression showed that STAT was a strong predictor of mortality (odds ratio [OR], 2.26; 95% CI, 1.94-2.64), whereas neonates had a greater baseline risk (OR, 3.88; 95% CI, 1.60-9.40); however, the STAT × neonate interaction suggested attenuated predictive performance in neonates (OR, 0.80; 95% CI, 0.63-1.01). Conclusions: STAT categories were associated with mortality overall but demonstrated attenuated discrimination in neonates, highlighting the limitations of procedure-only stratification in physiology-dominated subgroups.
