Real-World Therapeutic Hypothermia for Neonatal HIE: Neurodevelopmental Outcomes and Predictors.

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
aimThis study assessed neurodevelopmental outcomes in neonates with hypoxic-ischemic encephalopathy (HIE) treated with therapeutic hypothermia (TH) outside randomised controlled trials (RCTs). It also aimed to identify predictors of outcomes and evaluate TH practices across centres.
methodsA prospective, area-based observational study was conducted in eight Italian NICUs (2016-2021), including neonates treated with TH for any grade of HIE. A 2-year neurodevelopmental follow-up was performed. Severe functional disability (SFD) was defined as cerebral palsy (Gross Motor Function Classification Level > 2), cognitive score < 2 SD, bilateral blindness/deafness, or epilepsy. Demographic, clinical and MRI data were analysed.
resultsAmong 283 cooled infants, 11 (3.8%) died and 272 (96.2%) survived. HIE severity was mild (14.0%), moderate (76.1%) and severe (9.9%). Follow-up data were available for 232 (85.3%) survivors, with SFD diagnosed in 27 (11.6%). No infants with mild HIE developed SFD. Severe MRI anomalies were found in 51.9% of SFD cases, while 90.7% of non-SFD children had normal findings. cEEG/aEEG-confirmed seizures (OR = 12.9, CI 3.5-65.0) and severe MRI anomalies (OR = 0.24, CI 0.13-0.44) were strong SFD predictors (AUC = 0.95).
conclusionMortality and SFD rates were lower than in RCTs. Seizures and severe MRI anomalies predicted poor outcomes. Further RCTs are needed to refine treatment criteria.
