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
backgroundTransoral laryngeal surgery (TOLS) may lead to glottic insufficiency and scarring which often causes pronounced hoarseness and sometimes swallowing impairment. Injection laryngoplasty with autologous fat is an established method to restore glottic competence and thus improve voice and swallowing function. We hereby aim to demonstrate how laryngeal fat injection can be applied following TOLS.
methodAutologous fat is harvested via liposuction and then centrifuged for three minutes at 3000 rpm (rpm) to separate fat cells from liquid fat and debris. Fat cells are then transferred to 1 ml Luer-Lock syringes and injected into the altered larynx via a 20 Gauge (0,9 mm) diameter injection needle under microscopic or endoscopic view. The primary objective hereby is approximation of remaining tissue on the glottic plain. The secondary objective is injection into areas of scarified tissue due to the beneficial effect of Adipose-Derived Mesenchymal Stem Cells and possible restoration of physiological laryngeal tissue properties. Injection laryngoplasty with autologous fat tissue may improve laryngeal function after partial laryngeal resection by laser surgery. Special attention needs to be paid to the specific individual postoperative anatomy of the patient's larynx as this may differ profoundly from patient to patient.
