Validation of the UB-ROSC Score for Predicting OHCA Survival in Chiayi City, Taiwan.

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
Out-of-hospital cardiac arrest (OHCA) is a critical public health issue, with survival rates varying widely due to multiple well-established factors, including emergency medical service (EMS) system structure, bystander response, initial cardiac rhythm, and patient-level characteristics. This study evaluates the Utstein-Based Return of Spontaneous Circulation (UB-ROSC) score's performance in predicting sustained Return of Spontaneous Circulation (ROSC > 2 h) in a midsized Asian city where EMS delivery is standardized and geographic variation in access is minimal. A total of 209 OHCA cases from Chiayi City in 2024 were analyzed, using Utstein-aligned data to compute UB-ROSC scores. Predictive performance was assessed via receiver operating characteristic (ROC) curves, calibration intercept and slope, the Hosmer-Lemeshow goodness-of-fit test, and bootstrap internal validation, focusing on sustained return of spontaneous circulation (ROSC) (> 2 h). After excluding pediatric and traumatic cases, 209 cases were analyzed. The cohort was 60.3% male, with 47.8% witnessed arrests and 67.0% receiving bystander CPR. The UB-ROSC score demonstrated fair discrimination, with an area under the ROC curve (AUC) of 0.78 (95% confidence interval [CI]: 0.70-0.85), stable on bootstrap and cross-validation. The calibration slope was 0.90 (95% CI: 0.62-1.18) but the calibration intercept was +0.71 (95% CI: 0.36-1.05), and the Hosmer-Lemeshow test was significant (
