Effect of Food Deprivation on Plasma Cortisol, Carbohydrate Metabolism, and Histomorphology in Clarias batrachus.

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 nutritional status of fish is essential for its health, experimental studies, and aquaculture practices. The current study investigated the impact of food deprivation on biochemical parameters, histology of skin, gill, and kidney tissues, and ultrastructure of gills in Clarias batrachus. Fish were subjected to food deprivation for 2, 7, and 15 days resulting in (a) significant increase in plasma cortisol levels, (b) no significant changes in plasma osmolality and plasma glucose content, and (c) significant decrease in liver and muscle glycogen contents. A substantial damage was detected in skin, gill, and kidney tissues with histological alterations in a time-dependent manner. Skin tissue displayed melanomacrophage aggregation, excoriated epidermis and dermis. In gill tissue, epithelial lifting, edema, desquamation, deformed secondary lamellae, and lamellar hyperplasia were observed. Kidney tissue exhibited degenerated tubules, melanomacrophage aggregations, and shrunken renal tubule. Scanning electron microscopy revealed that food deprivation-induced marked presence of mucus, chloride cells, and pavement cells with well-defined microridges and microbridges following 2 days, opening of chloride cells was more prominent after 7 days, while more mucus secretion was observed after 15 days. After food deprivation, alterations in biochemical and histological parameters, and ultrastructural changes in target tissues reflect physiological and morphological disturbances in fish. The novelty of this study is that these parameters can be considered as biomarkers of feeding stress in fish and fish health and can provide important insights for better aquaculture practices.
