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
backgroundAnterior cruciate ligament reconstruction (ACLR) rates are rising, and quadriceps tendon (QT) autografts have gained popularity in recent years. Although QT autografts show objective and subjective outcomes comparable to hamstring tendon (HT) and bone-patellar tendon-bone (BPTB) autografts, nonrevision reoperations across graft types and their impact on patient-reported outcome measure (PROM) scores remain poorly studied. PURPOSE: To compare nonrevision reoperation rates and PROM scores between primary ACLR using HT, BPTB, and QT autografts at 2 years' follow-up. STUDY
designCohort study; Level of evidence, 3.
methodsIn this retrospective cohort study, 5653 primary ACLR procedures (2015-2022) were categorized by autograft type. Reoperations for extension deficit or pain, meniscal injuries, or cartilage injuries within 2 years were identified through medical records. Revision ACLR and graft failure were not included. Patient-reported outcomes were assessed preoperatively and at 2 years postoperatively using the Knee Injury and Osteoarthritis Outcome Score (KOOS). The minimal important change, patient acceptable symptom state, and treatment failure were evaluated using the KOOS
resultsThe QT group had a higher overall reoperation rate (19.2%) than the HT (8.9%) and BPTB (6.9%) groups (
conclusionQT autografts were associated with significantly higher reoperation rates for extension deficit or pain and inferior PROM scores compared with HT autografts at 2 years after primary ACLR.
