What About the Rheological Properties of PRP/Microfat Mixtures in Fat Grafting Procedure?
Article in Aesthetic plastic surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 grafting has emerged as a reference procedure in daily plastic surgery practice. Unpredictable fat resorption is the main clinical problem. For this purpose, the addition of PRP to enhance fat revascularization is now an easy and popular procedure. However, no consensus exists regarding the respective volume of fat and PRP used to obtain the ideal mixture. This study investigated the rheological properties of microfat mixed with different proportions of PRP. Results obtained were compared with commercialized hyaluronic acid fillers.
methodsMicrofat and PRP preparations were performed using standardized techniques. Lipoaspirate residue and blood were obtained from six patients undergoing aesthetic facial microlipofilling. Elastic modulus G' and tan δ (proportion of elasticity versus fluidity) were obtained for the following conditions: microfat alone and microfat mixed with 10, 30 or 50% of PRP.
resultsAn expected decrease in elastic modulus was observed by adding increase volumes of PRP. Two groups of products with different rheological properties were considered based on statistical differences highlighted regarding the value of G'. Mean tan δ varied from 0.20 ± 0.04 (microfat alone) to 0.28 ± 0.08 (50% microfat/50% PRP). Microfat mixed with 10% of PRP presents consistency comparable to stiffer fillers, whereas microfat mixed with 30 or 50% corresponds to softer fillers.
conclusionRheological differences were highlighted given the proportion of PRP added to the microfat. Further studies assessing the impact of increased doses of platelets in microfat/PRP mixtures on clinical outcomes should also be investigated. Our findings will help clinicians to choose a mixture that meets their specific needs for a given indication.
