Risk Factors for Donor-site Seroma Formation After Anterolateral Thigh Flap Harvest.

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
Background: The anterolateral thigh (ALT) flap is a versatile option for reconstructive surgery due to the availability of multiple tissue types and minimal donor-site morbidity. However, donor-site seroma formation remains a poorly understood complication, particularly with regard to its severity. In this study, we aimed to investigate the incidence, severity, and factors associated with seroma formation after ALT flap harvesting. Methods: We conducted a retrospective analysis of 150 patients who underwent ALT flap harvest between November 2020 and September 2023. Donor-site seromas were graded using the Clavien-Dindo classification, and patients were divided into 2 groups based on the presence or absence of seromas. Logistic regression analysis was performed to identify independent factors associated with seroma formation. Results: Seroma formation occurred in 18.0% of patients. Most cases (70.4%) were classified as Clavien-Dindo grade 1, requiring only conservative management, whereas 29.6% (5.3% of all patients) were classified as grade 3a or higher, necessitating surgical intervention. Male sex (odds ratio, 3.11; 95% confidence interval, 0.97-9.98; Conclusions: Fascia lata harvests larger than the skin paddle were associated with donor-site seroma formation with ALT flap harvests. Preoperative planning and careful fascia lata harvesting techniques are recommended to minimize complications.
