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
Malnutrition of protein and essential nutrients in children can lead to serious health problems. It significantly alters hepatic physiology and leads to impaired liver function. The present study investigated the underlying mechanism of malnutrition-induced steatohepatitis in a rat model. Weanling rats were divided into two groups. The control rats received a standard protein diet, while the other group was fed a low protein diet (LPD) for eight weeks. LPD significantly reduced the body and liver weights and altered the blood parameters. LPD resulted in elevated serum liver injury markers and lowered glucose, albumin, and total protein levels. The reduced levels of TIBC and TSI and upregulated expression of Hamp gene were observed in the LPD group. Histopathology revealed the severe fat accumulation in the hepatocytes, leading to inflammation and fibrognesis. LPD upregulated the de novo lipogenesis (Srebp1c, Fas, Acc, and Scd1) markers and oxidative stress in the hepatic tissue. The downregulation of Pgc1α, Tim23, and Tfam indicated mitochondrial dysfunction in the LPD group. Transcriptomic analysis revealed the upregulation of 7,545 genes in the LPD group mainly associated with metabolic dysfunction-associated steatotic liver disease (MASLD), beta-oxidation, AMPK signalling and oxidative phosphorylation. Hepatic lipidome revealed the elevated levels of various lipid species in the LPD group. Further, LPD altered the gut microbiome of rats and reduced the relative abundance of beneficial bacteria. The present study revealed that malnutrition induces hepatic steatoheptitis by altering the hepatic lipid metabolism and disrupting mitochondrial function and gut-liver axis.
