The association between BMI and BRAFV600E mutation may differ by primary tumor size.
Article in European thyroid journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objective: Previous reports suggest that a high body mass index (BMI) increases the risk of thyroid carcinoma. However, it remains unclear whether a high BMI is associated with the risk of the BRAFV600E mutation. We aimed to assess whether a high BMI is associated with an increased risk of the BRAFV600E mutation. Design and Methods: We screened 6558 PTC patients who had undergone BRAFV600E mutation testing between January 2009 and December 2017. After exclusion, 6438 PTC patients were enrolled. We used logistic regression, and restricted cubic spline plots of the adjusted odds ratios (ORs) were illustrated to model the relationship between BMI and the BRAFV600E mutation. Results: Of the 6438 patients, 5102 (79.2%) had the BRAFV600E mutation, and 4954 (76.9%) were female. The median BMI was 23.8 (21.6-26.2) kg/m2. The primary tumor size was ≤1 cm in 4226 patients (65.6%) and >1 cm in 2212 patients (34.4%). The BRAFV600E mutation was significantly associated with high BMI only in patients with a primary tumor size >1 cm (OR: 1.034; 95% CI: 1.003-1.065; P = 0.029), whereas no clear association was found in patients with a primary tumor size ≤1 cm (OR: 1.007; 95% CI: 0.984-1.030; P = 0.570). Gender was not a significant factor in either group. Conclusions: Our study found that a higher BMI was positively associated with the BRAFV600E mutation in patients with a primary tumor size >1 cm. These results suggest that the association between BMI and the BRAFV600E mutation status differs depending on primary tumor size. Significance Statement: Obesity has been suggested as a potential risk factor for thyroid carcinoma. The aim of this study was to assess the association between BMI and the BRAFV600E mutation. In this study, the BRAFV600E mutation was significantly associated with a high BMI only in a primary tumor size >1 cm (OR: 1.034; P = 0.029). No clear association was found in patients with a primary tumor size ≤1 cm (OR: 1.007; P = 0.570). The association between BMI and the BRAFV600E mutation status differs depending on the primary tumor size.
