Randomised clinical trial: Effect of administering platelet-rich fibrin to autologous fat tissue in injection laryngoplasty for vocal cord paralysis.
Article in Annals of medicine and surgery (2012), 2021. 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
The vocal cord in humans is essential in producing voice used in communication and interaction between us. Vocal cord paralysis causes dysphonia, which interferes with communication, causing disruptions towards social activity and daily activities. One of the managements for vocal cord paralysis is medialization and augmentation of the vocal cord through injection laryngoplasty. Autologous fat is one of the best fillers used in this procedure, but it is highly absorbable and can be reabsorbed very quickly when injected into body tissues. Platelet Rich Fibrin (PRF) is a biomaterial consisting of growth factors that are thought to improve fat tissue viability by increasing adipogenesis and angiogenesis. Improvement in fat viability will improve clinical outcomes after the laryngoplasty procedure, potentially reducing the number of repeated injections needed to achieve a satisfactory resolution to vocal cord paralysis. The study evaluates a combination of PRF and autologous microlobular fat compared with autologous microlobular fat alone on laryngoplasty. This single-blinded randomised control trial recruit a total of 18 patients, which are then randomised into the treatment and control groups. The evaluation was done via computerized acoustic analysis/Multidimensional Voice Program (MDVP) parameters and maximum phonation time. The MDVP results and maximum phonation time in both groups showed clinical improvement after the operation with no statistically significant differences.
