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: To evaluate the association of preoperative prophylactic transcatheter arterial embolization (PTAE) with perioperative blood loss and operative time in hemodynamically stable acetabular fractures, and to explore outcomes associated with different embolization strategies. Methods: We retrospectively analyzed 304 patients treated between January 2023 and March 2025, including 106 who underwent PTAE and 198 who underwent open reduction and internal fixation without preoperative embolization. Propensity score matching generated 89 matched pairs. Intraoperative blood loss, total drainage output, hidden blood loss, total blood loss, and operative time were compared. Separate multivariable linear regression models were used for total blood loss and operative time. Within the PTAE cohort, outcomes were also compared between superselective superior gluteal artery (SGA) embolization and internal iliac artery (IIA) trunk embolization. Results: Angiography identified occult vascular injuries in 15 of 106 PTAE patients (14.15%). After matching, PTAE was associated with lower intraoperative blood loss, total drainage output, hidden blood loss, and total blood loss, as well as shorter operative time (all Conclusion: In this propensity score-matched retrospective cohort, preoperative PTAE was associated with lower perioperative blood loss and shorter operative time. Superselective embolization of anatomically high-risk vessels may be a potential strategy for perioperative vascular management, but subgroup findings should be interpreted cautiously.
