1 · What the graph read from it

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.

2 · The registry

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

Ballooning degeneration (BD) of hepatocytes is a distinguishing histological feature associated with the progression of nonalcoholic fatty liver disease (NAFLD). Under the assumption that NAFLD severity is associated with metabolic-stress we explored the hypothesis that heat shock 27 kDa protein 1 (HSP27), a protein chaperone involved in stress resistance and cytoskeletal-remodeling, might be deregulated in ballooned hepatocytes. We observed that fasting plasma glucose (fpG) (p = 0.00002), total cholesterol (p = 0.02) and triglycerides (p = 0.01) levels, and female sex (p = 0.01) were significantly associated with the presence of BD. A logistic regression model showed that BD was independently associated with fpG (p = 0.002); OR per unit of glucose concentration 1.05, 95% confidence interval 1.02-1.09. Furthermore, BD was associated with a significant 2.24-fold decrease in the expression level of HSP27-mRNA in comparison with absence of ballooning, p = 0.002. Ballooned hepatocytes showed very low HSP27 immunoreactivity compared with hepatocyes without ballooning (p = 0.009); HSP27 immunoreactivity was inversely correlated with fpG levels (R: -0.49, p = 0.01). In conclusion, BD is associated with down-regulation of liver HSP27 gene and protein expression, suggesting that ballooned hepatocytes fail to ensure a robust physiological response to metabolic-induced stress.
