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
purposeTo compare clinical and functional outcomes of medial patellofemoral ligament (MPFL) reconstruction using a minimally invasive pedicled quadriceps tendon (QT) or patella double tunnel technique with semitendinosus tendon (ST) graft in patients with recurrent patella dislocation.
methodsA retrospective analysis was conducted on 51 patients who underwent MPFL reconstruction between 2014 and 2022, with a minimum 2-year post-operative follow-up. Patients were grouped as QT (n = 24) and ST (n = 27), alongside a control group of 24 healthy individuals. Kujala, Lysholm and Visual Analogue Scale (VAS) scores were evaluated. Isokinetic tests at 60° angular velocity were performed to calculate the limb symmetry index (LSI) and hamstring/quadriceps (H/Q) ratio.
resultsNo significant differences were found between groups regarding age, sex, body mass index, time to surgery, or number of dislocations (n.s). Mean Kujala (QT: 89.2 ± 8.9, ST: 85.4 ± 11.4), Lysholm (QT: 90.6 ± 9.4, ST: 87.9 ± 10.7), and VAS (QT: 0.83 ± 1.3, ST: 0.9 ± 1.1) scores showed no statistically significant differences between the groups (n.s). Extension LSI was significantly higher in QT (92.2 ± 10.0%) than ST (81.4 ± 16.4%, p = 0.024), as was flexion LSI (QT: 94.2 ± 10.9%, ST: 83.3 ± 17.5%, p < 0.01). H/Q ratios showed no significant differences between operated and non-operated sides (n.s). No redislocations or patellar fractures occurred. Apprehension signs were positive in two patients (7.4%) in ST and one patient (4.1%) in QT.
conclusionMPFL reconstruction with both ST and pedicled QT grafts yields successful results in well-selected patient groups. Unlike ST, reconstruction with QT results in extension and flexion strength in the operated extremity that is closer to the non-operated side and to the healthy control group. LEVEL OF EVIDENCE: Level III, retrospective case-control study.
