Investigation of the Effect of Mobile and Immobile Regions on Fat Graft Viability: An Experimental Study in a New Model.
Article in Aesthetic plastic surgery, 2024. 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
backgroundFat grafts are widely used in plastic, aesthetic and reconstructive surgery. Their unpredictable resorption is their main disadvantage. A review of the literature shows that there is a lack of research on the effect of mobile and immobile regions on fat graft survival in fat graft applications.
objectiveOur aim was to investigate the relationship of fat graft survival with mobile and immobile region in a new experimental model.
methodsTwenty-four male Wistar albino rats were randomly divided into two groups (n=12). Fat grafts were harvested from the right inguinal region of the rat. In Group 1, the fat graft was placed in the subcutaneous pouch formed in the scalp region of the rat. In Group 2, fat grafts were placed in the pouch formed in the posterior cervical region of the rat. At the end of 6 weeks, the weights and histopathology of the fat grafts were evaluated. Histopathological examinations were performed in a blinded fashion.
resultsThe weights of the fat grafts were found to be higher in Group 1. At the same time, histopathological examinations showed that vascular density was higher in Group 1. There was no statistically significant difference in other histopathological examinations.
conclusionThe mobile and immobile areas may have different effects on the survival of transplanted fat grafts. Sliding movement between muscle and skin in the mobile zone puts stress on the fat graft. In our study, the mobile site was shown to have a negative effect on the vascularity of the fat graft. It was observed that the vascular density was higher in the fat graft placed in the immobilised area. Further studies on the increase in vascularity can be carried out using the new experimental model we have created.
