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

objectiveThis study sought to correlate gallbladder (GB) Na+ and Cl-) fluxes with biliary lipid composition during the various stages of gallstone (GS) formation. SUMMARY BACKGROUND DATA: GS formation is associated with altered GB ion transport and increased biliary lipid and Ca2+ concentrations. Nonetheless, the longitudinal relationship between ion transport and biliary lipid changes during GS formation has not been defined.

methodsPrairie dogs were fed standard (n = 18) or 1.2% cholesterol-enriched (n = 30) diets for 4 to 21 days. Hepatic and GB bile were analyzed for lipids and Ca2+. Animals were designated either Pre-Crystal, Crystal, or GS based on absence or presence of crystals or GS, respectively. GBs were mounted in Ussing chambers, electrophysiologic parameters were recorded, and unidirectional Na+ and Cl- fluxes measured.

resultsShort-circuit current and potential difference were similar during Pre-Crystal and Crystal stages but significantly reduced during GS stage compared to controls and Pre-Crystals. Transepithelial resistance was similar in all groups. Net Na+ absorption was increased during Pre-Crystal but decreased during GS stage due to increased mucosa-to-serosa and serosa-to-mucosa flux, respectively. Increased serosa-to-mucosa flux of both Na+ and Cl- characterized the Crystal stage. Biliary lipids and Ca2+ increased progressively during various stages of GS formation and correlated positively with unidirectional fluxes of Na+ and Cl-.

conclusionGB epithelial ion transport changes sequentially during GS formation, with the early Pre-Crystal stage characterized by increased Na+ absorption, and the later Crystal stage accompanied by prosecretory stimuli on Na+ and Cl- fluxes, which may be due to elevated GB bile Ca2+ and total bile acids.
