1 · What the graph read from it

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.

2 · The registry

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: This study aimed to assess the predictive value of pulse pressure (PP) for identifying the critical administration threshold (CAT) in hemodynamically stable patients with active bleeding following blunt trauma. Methods: This retrospective study included hemodynamically stable blunt trauma patients treated from 2021 to 2022 in our hospital. Patients were grouped by CAT+ or CAT- status. Propensity score matching (PSM) was used to balance baseline characteristics. Logistic regression analyses evaluated the predictive value of PP, while receiver operating characteristic curve (ROC) analysis was performed to determine optimal thresholds in elderly patients (age >60 years). Results: Of 456 patients, 65 (14.3%) were classified as CAT+. PP ≤40 mmHg was an independent predictor of CAT+ before PSM (OR = 5.931; 95% CI, 2.648-13.284; P < 0.001) and after PSM (adjusted OR = 4.579; 95% CI, 1.193-10.958; P = 0.016). In elderly patients, the optimal PP threshold for CAT+ was ≤41.5 mmHg, with an area under the curve (AUC) of 0.822 (95% CI, 0.724-0.921). Conclusion: PP is a reliable predictor of critical hemorrhage in hemodynamically stable blunt trauma patients and elderly subgroups, supporting its use in trauma care.
