Biliary lipids, lithogenic index and biliary drug concentrations during etofibrate and bezafibrate treatment.
Trial report in European journal of drug metabolism and pharmacokinetics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Hypolipidemic drugs like etofibrate and bezafibrate may induce lithogenic bile and increase the risk of gallstone formation. In this study, biliary lipids, lithogenic index and biliary drug concentrations were investigated in 6 hyperlipidemic patients after cholecystectomy. Patients were treated once daily for 5 days with either 500 mg/day etofibrate or 400 mg/day bezafibrate. Hepatic bile was collected for 6 days via T-drainage in 4 hourly aliquots. In the patients treated with etofibrate, the range of the lithogenic index remained stable with 0.89-1.69 before and 0.78-1.51 after 5 day drug therapy. In the bezafibrate group, the range of the lithogenic index rose from 0.81-1.40 to 1.26-1.66 mainly as a result of an increase of biliary cholesterol concentrations. Biliary drug concentrations were substantially higher under bezafibrate treatment than under etofibrate treatment. In conclusion, the fibrate drugs, etofibrate and bezafibrate, are different with regard to lithogenicity of bile and extent of biliary excretion. The safety profile of etofibrate may be preferably compared to other fibrate drugs.
