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

Moxifloxacin (MXF) is a fluoroquinolone antibiotic that is effective against respiratory infections. However, the mechanisms of MXF lung diffusion are unknown. Active transport in other tissues has been suggested for several members of the fluoroquinolone family. In this study, transport of MXF was systematically investigated across a Calu-3 lung epithelial cell model. MXF showed polarized transport, with the secretory permeability being twice as high as the absorptive permeability. The secretory permeability was concentration dependent (apparent P(max) = 13.6 x 10(-6) cm x s(-1); apparent K(m) = 147 microM), suggesting saturated transport at concentrations higher than 350 microg/ml. The P-glycoprotein inhibitor PSC-833 inhibited MXF transport in both directions, whereas probenecid, a multidrug resistance-related protein inhibitor, appeared to have no effect in the Calu-3 model. Moreover, rifampin, a known inducer of efflux transport proteins, upregulated the expression of P-glycoprotein in Calu-3 cells and enhanced MXF active transport. In conclusion, this study clearly indicates that MXF is subject to P-glycoprotein-mediated active transport in the Calu-3 model. This P-glycoprotein-dependent secretion may lead to higher MXF epithelial lining fluid concentrations than those in plasma. Furthermore, drug-drug interactions may be expected when MXF is combined with other P-glycoprotein substrates or modulators.
