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: Total knee arthroplasty (TKA) techniques and implant designs vary significantly regarding management of the posterior cruciate ligament (PCL). The clinical implications of routinely resecting or selectively balancing the PCL in modern congruent or pivot designs remain debated. This study compares clinical outcomes between routine PCL resection and selective PCL balancing using a medial congruent polyethylene. Methods: A retrospective matched-cohort study was conducted with 304 patients undergoing primary unilateral TKA between September 2020 and April 2024. Patients were matched based on demographics (age, gender, body mass index, Charlson Comorbidity Index, and the Risk Assessment and Prediction Tool score) and based on preoperative Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) scores. Postoperative outcomes were analyzed, including patient-reported outcome measures, physical therapy parameters, readmission rate, overall complication rate, and 90-day return to operating room. Results: The PCL resection group had significantly longer operative times (86.5 vs 73.9 minutes, Conclusions: Routine PCL resection in TKA utilizing a medial congruent polyethylene design did not influence patient-reported outcomes compared to selective balancing and should be left up to surgeon preference.
