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
purposeSous vide is a cooking method, which enhances heat flow and enables cooking at regulated temperatures in plastic pouches that have been vacuum-sealed. This procedure can be used as an alternative to bone maceration because of this property. This study describes how fresh and embalmed human specimens can be macerated and cleaned using sous vide.
methodsEighth head and neck, seven upper, and five lower extremity specimens from ten fresh and three embalmed cadavers at the Department of Anatomy of the Koç University School of Medicine were used. Soft tissues were removed, and specimens were vacuum sealed in plastic pouches filled with water and dishwashing detergent solution. Maceration was set at 65 °C for three to four days with a commercial sous vide device. Blunt instruments were used to remove any leftover soft tissue in between every maceration session. Following the maceration, a concentrated acetone solution was used for further degreasing.
resultsThe method successfully cleaned all fresh specimens. While some embalmed specimens were completely cleaned, maceration of extremely dried out embalmed cadavers were suboptimal. It took three to five maceration rounds to completely clean small (vertebrae, carpal bones etc.) and large (skulls, femurs, humeri etc.) bones.
conclusionSous vide successfully cleaned fresh and embalmed human bones. It allowed easy monitoring of the process, reduced the exposure of staff to unpleasant odor and biological waste, and minimized the need for cleaning by using consumables.
