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

objectivesDetermine the bidirectional transfer of oseltamivir carboxylate (OC) across term human placenta and its distribution between the tissue, maternal and fetal circuits.

methodsThe technique of dual perfusion of placental lobule (DPPL) in its recirculating mode was utilized to determine the transfer of the drug. OC (350 ng/mL) was co-perfused with its [(3)H]-isotope and the marker compound antipyrine (AP, 20 µg/mL) together with its [(14)C]-isotope. The concentrations of OC and any of its metabolite(s) formed during perfusion were determined in the tissue, maternal and fetal circuits by liquid scintillation spectrometry following their separation by High Performance Liquid Chromatography (HPLC).

resultsThe distribution of OC following its perfusion in the Maternal-to-Fetal direction for 4 h was as follows: 21 ± 4% of the drug was transferred to the fetal circuit, 13 ± 5% was retained by the perfused lobule, and 66 ± 4% remained in the maternal circuit. The normalized transfer of OC to that of AP (Clearance index) in the maternal-to-fetal direction was (0.47 ± 0.11) and was not different from its transfer from the fetal-to-maternal direction (0.47 ± 0.06) suggesting that involvement of placental efflux transporters is unlikely.

conclusionsOC crosses human placenta. As the transfer rate of OC is 47% of the freely diffusible AP, it is likely that fetus could be exposed to OC during pregnancy.
