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
backgroundPatellar tendon rupture is an uncommon injury that usually requires surgical repair, but no consensus exists regarding the ideal repair technique. Suture anchor repair and the transosseous suture method have be widely used, but the suture anchor technique may cause anchor pull-out, while the transosseous suture method may result in insufficient suture strength. Therefore, we propose and evaluate the efficacy of combined repair technique with two suture anchors and three transosseous sutures for patellar tendon repairs.
methodsWe conducted a retrospective cohort study of patients who received surgery for acute patellar tendon rupture at the inferior pole of the patella between January 2016 and December 2020. All patients underwent a standardized integrated knee extensor mechanism combined repair technique by the same surgeon with 2 suture anchors and 3 transosseous sutures. Radiology, complications, and patient-reported outcomes were recorded. Clinical outcomes were measured using range of motion (ROM), patient satisfaction, Visual Analog Scale (VAS) pain scores, Knee Society Function Score (KSS-F), International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score.
resultsTotally 40 patients were enrolled with an average age of 33.95 years. Mean follow-up duration was 60 months (range: 36 to 72 months). The risk of complications was 7.5% (3/40). Mean ROM improved from 45.65 ± 10.66 preoperatively to 127.25 ± 3.99 postoperatively (mean ± SD, p < 0.001). Mean postoperative VAS pain score, KSS-F score, IKDC score, Lysholm score and Tegner score significantly improved (p < 0.001). The Caton Deschamps Index (CDI) significantly decreased from 1.74 ± 0.19 preoperatively to 1.11 ± 0.06 postoperatively (p < 0.001). Postoperative MRI revealed evident healing between the patellar tendon and the inferior pole of the patella.
conclusionsThe combined repair technique demonstrated reliable mid-term outcomes with satisfactory functional recovery, radiological healing, and a low complication rate. This technique may serve as a practical and effective option for proximal patellar tendon ruptures.
