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
backgroundTotal knee arthroplasty (TKA) in valgus deformity remains technically challenging due to capsulo-ligamentous imbalances. This multicenter propensity score-matched study aimed to compare functional and radiographic outcomes of TKA for valgus knees versus a matched control group of varus knees, and identify independent prognostic factors. MATERIALS AND
methodsIn this retrospective multicenter cohort study with propensity score matching (Monastir and Mahdia University Hospitals, between 2015 and 2022), we included 120 patients (132 knees) who underwent TKA for osteoarthritis with valgus deformity. A control group of 120 patients (132 knees) operated for varus deformity was constituted using propensity score matching (age, sex, BMI, preoperative IKS score, year of surgery). The primary outcome was the 2011 IKS score at a mean follow-up of 5.2 ± 2.5 years. Kaplan-Meier survival curves were generated. Multivariate logistic regression identified prognostic factors.
resultsAfter matching, both groups were comparable for all demographic variables. The global IKS score improved from 91.3 ± 14.2 to 166.5 ± 15.8 in the valgus group, with no significant difference compared to the varus group (167.2 ± 14.9; p = 0.68). Five-year implant survival was 98.5% (95% CI [96.2-99.4]) in the valgus group versus 99.2% (95% CI [97.1-99.8]) in the varus group (p = 0.54). Multivariate analysis identified three independent factors associated with excellent functional outcome: absence of postoperative laxity (OR = 4.3; 95% CI [2.1-8.9]; p < 0.001), rehabilitation duration within three months (OR = 3.4; 95% CI [1.7-6.9]; p = 0.002), and patellar resurfacing (OR = 2.2; 95% CI [1.2-4.3]; p = 0.02).
conclusionAfter propensity score matching, TKA for valgus deformity achieves functional outcomes and 5-year survival comparable to TKA for varus deformity. The quality of ligamentous balancing and early intensive rehabilitation are the major determinants of success. LEVEL OF EVIDENCE III: (Retrospective comparative study with propensity score matching).
