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

purposeThe purpose of this study is to clarify the impact of P-gp and Oatp on intestinal absorption of the beta(1)-adrenoceptor antagonist talinolol.

methodsP-gp-mediated transport was measured in LLC-PK1/MDR1 cells. Oatp-mediated uptake was evaluated with Xenopus oocytes expressing Oatp1a5. Rat intestinal permeability was measured by the in situ closed loop method. In vivo absorption was pharmacokinetically assessed by measuring plasma concentration after oral administration in rats.

resultsIn LLC-PK1/MDR1 cells, the permeability of talinolol was markedly higher in the secretory direction than in the absorptive one. The uptake of talinolol by Xenopus oocytes expressing Oatp1a5 was significantly increased compared with that by water-injected oocytes. Naringin inhibited talinolol uptake by Oatp1a5 (IC (50) = 12.7 microM). The reported IC (50) value of naringin for P-gp-mediated transport of talinolol is approximately 2,000 microM. Rat intestinal permeability of talinolol was significantly decreased in the presence of 200 microM naringin, but was significantly increased by 2,000 microM naringin. Similar results were obtained in in vivo absorption studies in rats.

conclusionThe absorption behavior of talinolol can be explained by the involvement of both P-gp and Oatp, based on characterization of talinolol transport by Oatp1a5 and P-gp, and the effects of naringin.
