BMI, Sex as Predictors of Anterolateral Thigh Free Flap Thickness for Oropharyngeal Reconstructions.

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
objectiveTo evaluate the relationship between body mass index (BMI), sex, and anterolateral thigh free flap (ALTFF) thickness, and to determine their impact on the use of ALT and super-thin ALT (STALFF) flaps for oral and oropharyngeal reconstruction.
methodsNinety-four patients who underwent ALTFF, super thin-ALTFF (ST-ALTFF), or radial forearm free flap (RFFF) reconstruction following resection of oral cavity and oropharyngeal squamous cell carcinoma were included. Preoperative PET/CT scans were analyzed to measure ALTFF thickness at three points along the thigh: the proximal fourth (Point A), midpoint (Point B), and distal fourth (Point C) of the line extending from the anterior superior iliac spine to the superior lateral surface of the patella. Statistical analyses included chi-squared, t-tests, ANOVA, and Pearson's correlation to assess associations between BMI, sex, and flap thickness.
resultsForty patients (42.5%) underwent ALTFF reconstruction, 18 had ST-ALTFF (19.1%), and 36 (38.3%) received RFFF. Pearson's correlation confirmed a strong positive relationship between BMI and flap thickness at all points (r > 0.62). Although BMI did not differ significantly between sexes (p = 0.066), females had significantly thicker flaps at all measured points (p < 0.0001).
conclusionBMI and sex are reliable predictors of ALTFF thickness and influence flap selection. Integrating these factors into preoperative planning optimizes patient selection for free flap type choice, minimizing intraoperative modifications and improving reconstructive outcomes.
