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
Most cystic fibrosis (CF) patients show an exocrine pancreatic insufficiency that results in lower enzyme and bicarbonate secretion. To test whether an altered function of nutrient transporters might additionally attribute to the lower bodyweight of CF patients we investigated electrogenic absorption of alanine, glycyl-glutamine, glucose and the effect of pH on nutrient absorption by Ussing chambers in a CF mouse model carrying the Cftr TgH(neoim)Hgu mutation. The electrogenic transport of all three nutrients was similar between the D2.129P2(CF/3)-Cftr TgH(neoim)Hgu congenic strain and DBA/2J mice as well as between the B6.129P2(CF/3)-Cftr TgH(neoim)Hgu congenic strain and C57BL/6J mice. This indicates that the Cftr TgH(neoim)Hgu mutation does not affect the electrogenic absorption of alanine, glycyl-glutamine and glucose. In contrast, electrogenic nutrient absorption was reduced in the CF/1-Cftr TgH(neoim)Hgu and CF/3-Cftr TgH(neoim)Hgu inbred strains compared to the HsdOla:MF1, D2.129P2(CF/3)-Cftr TgH(neoim)Hgu and B6.129P2(CF/3)-Cftr TgH(neoim)Hgu strains, whereas no difference was found among the wild-type strains. This indicates that not the Cftr TgH(neoim)Hgu mutation but differences in the genetic background of the CF/1-Cftr TgH(neoim)Hgu and CF/3-Cftr TgH(neoim)Hgu strains compared to HsdOla:MF1, D2.129P2(CF/3)-Cftr TgH(neoim)Hgu and B6.129P2(CF/3)-Cftr TgH(neoim)Hgu strains are associated with the differences in electrogenic nutrient absorption. The electrogenic absorption of alanine, glycyl-glutamine and glucose was not influenced by an acidic pH (5.4) compared to absorption at pH 7.4.
