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
Background: Rib fractures are a frequent consequence of thoracic trauma. Although surgical stabilization of rib fracture (SSRF) is the established treatment for severe cases, selecting appropriate rib-encircling plates remains a predominantly subjective, intraoperative process. This empirical assessment carries an inherent risk of implant-anatomy mismatch. This study aimed to evaluate the feasibility and accuracy of a three-dimensional (3D) "virtual overlapping" technique for determining optimal plate dimensions prior to surgery. Methods: This prospective cohort study enrolled 29 consecutive adult patients with multiple displaced rib fractures (displacement ≥1 shaft width). 3D rib models were generated from preoperative computed tomography (CT) scans. Digital templates of titanium and memory-alloy plates were virtually matched to the fracture sites to preoperatively select the optimal implant size. The primary outcome was intraoperative concordance between the pre-selected size and the actual implanted plate. Results: The cohort included 29 patients (21 males, 8 females; mean age, 56.2±14.6 years). Comprehensive preoperative planning, specifically targeting 2-3 critical fracture ends, required approximately 1.5-2 hours per case. Preoperative virtual sizing was successfully performed for all patients. Intraoperative verification confirmed that the pre-selected plates achieved secure fixation and appropriate anatomical fit in all 29 cases (100% concordance), with no need for intraoperative hardware exchange. Postoperative CT confirmed precise plate apposition to the rib surface, with no need for intraoperative hardware exchange. Conclusions: Integrating 3D virtual overlapping technology into preoperative planning is feasible and enables accurate plate sizing. This approach offers an objective method to reduce intraoperative uncertainty and potential sizing errors in rib fracture surgery.
