Early Prediction of High-flow Nasal Cannula Failure Using Pediatric-modified HACOR Score in Children with Acute Hypoxemic Respiratory Distress: A Prospective Observational Study.

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: Delayed recognition of treatment failure with heated humidified high-flow nasal cannula (HFNC) in pediatric acute respiratory distress can lead to adverse outcomes. This study presents and verifies a pediatric-modified [heart rate, acidosis, consciousness, oxygenation, respiratory rate (HACOR)] (p-HACOR) score as an instrument for the early prediction of HFNC therapy failure in children experiencing acute hypoxemic respiratory distress. Design: Single-center prospective observational study. Setting: Pediatric intensive care unit (PICU) of a tertiary care teaching hospital in Pune, India. Patients: One hundred and forty-six children (aged 1 month-18 years) admitted to PICU with acute hypoxemic respiratory distress necessitating HFNC therapy. Interventions/measurements: The p-HACOR score-a composite metric incorporating heart rate, acidity, consciousness, oxygenation, and the respiratory rate adjusted for age-specific criteria was assessed at designated intervals: Before initiation and at 1, 6, 12, 24, 36, and 48 hours following commencement of HFNC therapy. Results: Treatment failure was observed in 23 patients (15.8%), with 83% necessitating intubation within 1-2 hours after therapy commencement. The p-HACOR score exhibited superior predictive ability at 1 hour postinitiation, with 91.3% sensitivity, 83.74% specificity, and 84.93% diagnostic accuracy [area under the curve (AUC) 0.951, Conclusions: The p-HACOR score may be useful as an early indicator of HFNC therapy failure. Its predictive ability was noted to be best at 1 hour postinitiation of HFNC, suggesting its potential for contributing to early decision-making regarding HFNC failure.
