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
This study investigated the physicochemical properties and volatile components of duck blood powder to determine its quality characteristics based on drying methods. The drying methods of duck blood samples used were freeze drying (FD), hot air drying (HD), spray drying (SD), and vacuum drying (VD). Duck blood powder treated with HD presented the lowest lightness and the highest carbonyl content. The VD-treated powder exhibited the highest water activity and redness. The composition of volatile compounds in duck blood varied based on the drying method, with VD presenting the highest total relative concentration but the least number of identified compounds. The most abundant compound was d-limonene, which was found in all the samples, followed by hexanal in VD and SD, p-xylene in FD, and trimethylamine in HD. Principal component analysis and heatmap analysis demonstrated that duck blood samples processed using different drying methods exhibited distinct volatile compound profiles, with HD, FD, SD, and VD samples associated with specific chemical groups. Multiple factor analysis revealed distinct correlations between drying methods and the physicochemical properties of duck blood, with VD samples showing higher water activity, aldehydes, and ketones, whereas HD samples exhibited increased carbonyl content and acids, highlighting the influence of heat on protein oxidation. VD method, therefore, presents excellent characteristics in terms of time and quality during the powdering process to increase the industrial utilization of duck blood. These findings provide valuable insights for the food industry, enabling the selection of appropriate drying methods that preserve the desired qualities of duck blood, thereby enhancing its commercial viability and potential application in a variety of food products.
