Body mass index and knee arthroplasty.
Article in Journal of clinical orthopaedics and trauma, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectivethis study aims to evaluate the relationship between body mass index (BMI), age at which knee joint arthroplasty is performed and complications. The hypothesis is that the higher the BMI, the greater likelihood that the patient will require surgery at an earlier age.Methods: this is a cohort study with all patients who underwent a primary knee arthroplasty, between August 2013 and February 2019, in a tertiary level university hospital. Association between BMI, age and complications were analyzed. Quality of life of patients was also evaluated with the Oxford Knee Score (OKS).
results565 primary total knee replacements (TKR) were performed. A cut-off point was found in BMI of 30; 348 patients had a BMI ≤30 and 173 patients had a BMI >30. When comparing the two groups, a statistically significant difference (p = 0.0186) was found in the age at which the TKR was performed. There was a significant improvement for both groups in functional score (Oxford knee score). Additionally, intra and post-operative complications showed no statistically significant difference.
conclusionpatients with BMI greater than 30 required primary knee arthroplasty at a younger age (average: 3.5 years), compared to patients with a lower BMI. Obesity does not appear to confer and independent risk for surgery in the short and mid-term. Knee arthroplasty improves significantly quality of life in the short and mid-term, regardless of their BMI, as measured with the OKS.
