Ultrasonographic Quantification of Reduction in Subcutaneous Fat Thickness Following Large-Volume Liposuction.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLarge‑volume liposuction is widely performed for abdominal contouring, yet objective, site‑specific quantification of subcutaneous fat reduction remains limited. Ultrasonography (USG) offers a practical, radiation‑free method for serial assessment, but its postoperative utility is under‑reported.
objectiveThis study aimed to quantify changes in abdominal subcutaneous fat thickness following large‑volume liposuction using USG and to evaluate associated changes in waist circumference, complications, and patient satisfaction.
methodsA prospective observational study was conducted on 50 patients (21-45 years) undergoing large‑volume abdominal liposuction (>5 L aspirate). Subcutaneous fat thickness was measured ultrasonographically at four standardized abdominal sites (supra‑umbilical (S), infra‑umbilical (I), right (R), and left (L)), pre‑operatively, one week, one month, and six months. Waist circumference was recorded at six months. Complications and patient satisfaction were documented. Repeated‑measures ANOVA assessed changes over time, and Pearson correlations evaluated associations between fat‑thickness reduction and waist‑circumference change.
resultsSignificant reductions in subcutaneous fat thickness were observed at all sites (p < 0.001), with mean reductions of 36%-44% at six months. Early maximal reductions at one week were followed by partial rebound at one month and stabilization by six months, reflecting edema resolution and tissue remodeling. Waist circumference decreased by a mean of 9.82 cm (≈10%). Correlations between waist‑circumference reduction and ultrasonographic fat‑thickness changes were weak and non‑significant, indicating that circumferential measures do not reliably reflect localized fat removal. Postoperative seromas/hematomas occurred in 84% at one week and resolved by one month. No major complications were observed. Patient satisfaction at six months was 96%.
conclusionLarge‑volume abdominal liposuction produces substantial and durable reductions in subcutaneous fat thickness and waist circumference. USG is a reliable, accessible, and cost‑effective modality for objective, site‑specific postoperative assessment, outperforming waist circumference in detecting localized fat‑layer changes. Larger studies with extended follow‑up and comparative imaging may further refine its role in body‑contouring evaluation.
