Redistribution of Gaze Patterns in Facial Localized Scleroderma Following Autologous Fat Transfer: An Eye-Tracking Study.
Observational study in Aesthetic plastic surgery, 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.
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
backgroundThe study aimed to use eye-tracking technology objectively quantifying changes in visual attention patterns in observers viewing faces of patients with facial localized scleroderma (LoS) before and after autologous fat transplantation (AFT).
methodsIn this retrospective observational study, preoperative and postoperative standardized photographs of 30 patients with facial localized scleroderma (LoS) were presented to 50 observers. Gaze data were recorded using an eye tracker. Fixation proportions were analyzed for all affected regions and for specific facial subunits.
resultsA total of 30,266 fixation points were recorded. Postoperatively, the fixation proportion on the affected hemiface significantly decreased by 4.92% (p<0.05), with a concomitant increase in fixations redirected toward the unaffected side. Furthermore, an increase of 2.39% (p<0.05) in fixation proportion was observed in the central T-zone (periorbital and nasal regions). Subunit analysis revealed reductions in fixations on the affected cheek (16.12% to 10.39%, p<0.05) and forehead (17.18% to 13.23%, p<0.05). Stratified analysis showed that severe dermal atrophy and severe dyspigmentation were associated with less postoperative fixation reduction, whereas fixation reduction did not differ significantly by subcutaneous atrophy severity.
conclusionAFT alters observers' visual attention by reducing fixations on the affected facial areas and redirecting gaze toward the unaffected side and the central T-zone. This shift suggests a partial redistribution of social-perceptual gaze patterns toward a more typical facial viewing pattern.
