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
introductionTotal knee arthroplasty (TKA) is a common procedure for advanced knee osteoarthritis. Although TKA outcomes have improved, variability remains, influenced by factors like patient comorbidities, age, and sex. One potential contributor to outcome variability is the surgeon's fellowship training. This study examines the relationship between orthopaedic fellowship types and clinical outcomes following TKA, focusing on complications, readmissions, and implant survival.
methodsThis retrospective cohort study used the PearlDiver Database (2010 to 2022) to identify TKA patients. Surgeons were classified based on fellowship training in arthroplasty, trauma, or nonarthroplasty/nontrauma specialties. Exclusion criteria included patients younger than 50, with concurrent trauma, neoplasms, infections, or lacking 90 days of follow-up. Ninety-day adverse events, including any, serious, and minor complications, and readmissions, were assessed. Multivariable analyses controlled for age, sex, and comorbidities. Five-year implant survival was evaluated using Kaplan-Meier analysis and compared with a log-rank test.
resultsA total of 1,180,690 TKA patients were analyzed. Procedures were performed by arthroplasty-trained surgeons (66,654 [5.7%]), trauma-trained surgeons (3,857 [0.3%]), and nonarthroplasty/nontrauma surgeons (1,110,179 [94.0%]). Surgeries by arthroplasty-trained surgeons had markedly lower rates of any (odds ratio [OR]: 0.77 ), serious (OR 0.74), and minor (OR 0.81) adverse events compared with nonarthroplasty/nontrauma surgeons (P < 0.001). Five-year implant survival was lower in the trauma cohort (94.83%) compared with the arthroplasty (96.71%) and nonarthroplasty/nontrauma cohorts (96.82%; P < 0.001). DISCUSSION: Fellowship training in arthroplasty was associated with lower complication rates, suggesting that surgeon specialization and/or associated care algorithms may be relevant variables. Further investigation is needed to optimize patient outcomes and validate these findings.
