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
purposeThe purpose of this study was to determine if prior manipulation under anaesthesia (MUA) and/or lysis of adhesions (LOA) was associated with an increased risk of re-revision following index revision total knee arthroplasty (TKA) in patients that had a diagnosis of arthrofibrosis.
methodsThe PearlDiver Mariner database was queried by Current Procedural Terminology (CPT) and International Classification of Disease (ICD) codes to identify patients who had a diagnosis of arthrofibrosis at the time of revision TKA. Patients were divided into two groups: those with prior MUA and/or LOA and those without prior MUA and/or LOA. The groups were 1:3 propensity score matched by age, gender, anemia, and Elixhauser Comorbidity Index (ECI). The primary outcome was incidence of re-revision TKA at 5 years. Secondary outcomes included periprosthetic joint infection (PJI) at 6 months and 5 years, 90-day hospital readmission, and the incidence of deep vein thrombosis (DVT), blood transfusion, and acute kidney injury (AKI) at 6 months. Logistic regression was used to determine predictors of re-revision TKA.
resultsAfter propensity matching, 2622 patients with a diagnosis of arthrofibrosis underwent index revision TKA without prior MUA and/or LOA and 874 patients underwent index revision after a prior LOA and/or MUA. The incidence of re-revision TKA at 5 years in patients with prior MUA and/or LOA (20% vs. 14%; OR 1.5, 95% confidence interval [CI] [1.3-1.9], p < 0.001) was significantly higher compared to patients with no prior MUA and/or LOA. Predictors of re-revision were age, ECI, and prior MUA and/or LOA (OR: 1.5, 95% CI [1.2-1.9]) (R
conclusionA history of prior MUA and/or LOA, older age, and ECI are associated with a significantly higher risk of re-revision TKA in patients that have a diagnosis of arthrofibrosis at the time of index revision TKA. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
