The Effect of Body Mass Index on Outcomes of Isolated Medial Patellofemoral Ligament Reconstruction.
Article in Orthopaedic journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The effect of body mass index (BMI) on complication risk, recurrent instability risk, and patient-reported outcomes (PROs) after surgical intervention for recurrent patellar instability is unclear. Purpose/Hypothesis: The purpose was to evaluate the differences in complications, recurrence, and PROs in obese and nonobese patients undergoing isolated medial patellofemoral ligament reconstruction (MPFLR). It was hypothesized that obesity is associated with increased complication risk, increased risk of recurrent patellar instability, and poorer PROs after MPFLR. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review identified all patients who underwent isolated MPFLR over an 8.5-year period at an academic medical center. Records were reviewed for demographic, physical examination, radiographic, surgical, and clinical outcome data. Patients were contacted to collect PROs, including the Norwich Patellar Instability score, Marx activity scale score, and Knee injury and Osteoarthritis Outcome Score (KOOS). Patients were stratified by BMI (<30 and ≥30 kg/m Results: The records of 107 patients were analyzed in this investigation. Complication rates were similar across groups. Patients with a BMI ≥35 kg/m Conclusion: No significant differences in complications or repeat dislocation risk after isolated MPFLR were noted based on BMI ≥30 or <30 kg/m
