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
backgroundEarly recognition of septic shock is crucial for improving outcomes in children with sepsis. This study aimed to compare the predictive performance of the Pediatric Risk of Mortality-III (PRISM-III), Phoenix Sepsis Score (PSS), and pediatric Sequential Organ Failure Assessment (pSOFA) scores for septic shock in Vietnamese children.
methodsA cross-sectional study was conducted on 86 children aged 2-months to 15-years with sepsis (including 23 with septic shock) admitted to a pediatric intensive care unit. Septic shock classification was performed independently and single ‒ blinded to score calculations to minimize assessment bias. The PSS and pSOFA were calculated using the worst parameters within the first 6-hours, and PRISM-III within the first 24 hours of admission. Discriminatory ability was assessed by the Area Under the Receiver Operating Characteristic Curve (AUROC). Multivariable logistic regression and calibration analyses were performed. Calibration results should be interpreted cautiously due to the small sample size.
resultsThe PSS showed the highest AUROC (0.867, 95 % CI: 0.777-0.931), followed by PRISM-III (0.826, 95 % CI: 0.729-0.899) and pSOFA (0.791, 95 % CI: 0.690-0.871); pairwise comparisons were not statistically significant. The PSS demonstrated the highest sensitivity (95.7 %) and negative predictive value (97.6 %), while PRISM-III had the highest specificity (90.5 %) and positive predictive value (70.0 %). In multivariable analysis, both PSS (Odds Ratio, OR = 2.78) and PRISM-III (OR = 1.23) were independent predictors of septic shock.
conclusionsThe PSS and PRISM-III provide complementary value. A two-step approach using the sensitive PSS for initial screening and the specific PRISM III for confirmation may enhance early septic shock recognition in resource-limited settings.
