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

Pharmacological doses of fibroblast growth factor (FGF) 21 effectively normalize glucose, lipid and energy homeostasis in multiple animal models with many benefits translating to obese humans with type 2 diabetes. However, a role for FGF21 in the regulation of bile acid metabolism has not been reported. Herein, we demonstrate AAV-mediated FGF21 overexpression in mice increases liver expression of the key bile acid producing enzyme, Cyp7a1, resulting in an increased bile acid pool. Furthermore, in cholecystectomized mice, FGF21-mediated bile acid pool increase led to increased transit of bile acids into colon. We elucidate that the mechanism of FGF21 induced bile acid changes is mainly through antagonizing FGF15/19 function on liver βKlotho/FGFR4 receptor complex; thus inhibiting FGF15/19-mediated suppression of Cyp7a1 expression. In conclusion, these data reveal a previously unidentified role for FGF21 on bile acid metabolism and may be relevant to understand the effects of FGF21 analogs in clinical studies.
