Ostα-/- mice are not protected from western diet-induced weight gain.
Article in Physiological reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Organic solute transporterα-OSTβ is a bile acid transporter important for bile acid recycling in the enterohepatic circulation. In comparison to wild-type mice, Ostα(-/-) mice have a lower bile acid pool and increased fecal lipids and they are relatively resistant to age-related weight gain and insulin resistance. These studies tested whether Ostα(-/-) mice are also protected from weight gain, lipid changes, and insulin resistance which are normally observed with a western-style diet high in both fat and cholesterol (WD). Wild-type and Ostα(-/-) mice were fed a WD, a control defined low-fat diet (LF) or standard laboratory chow (CH). Surprisingly, although the Ostα(-/-) mice remained lighter on LF and CH diets, they weighed the same as wild-type mice after 12 weeks on the WD even though bile acid pool levels remained low and fecal lipid excretion remained elevated. Mice of both genotypes excreted relatively less lipid when switched from CH to LF or WD. WD caused slightly greater changes in expression of genes involved in lipid transport in the small intestines of Ostα(-/-) mice than wild-type, but the largest differences were between CH and defined diets. After WD feeding, Ostα(-/-) mice had lower serum cholesterol and hepatic lipids, but Ostα(-/-) and wild-type mice had equivalent levels of muscle lipids and similar responses in glucose and insulin tolerance tests. Taken together, the results show that Ostα(-/-) mice are able to adapt to a western-style diet despite low bile acid levels.
