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

Rodents eliminate antiepileptic drugs (AEDs) faster than humans, creating challenges for designing clinically relevant protocols. Half-lives of AEDs in immature mice are unknown. The pharmacokinetics of commonly used AEDs were examined in CD1 mice using a single-dose protocol at postnatal day 19. After intraperitoneal therapeutic dosing, blood serum concentrations spanning 1-48 h post-administration and corresponding brain tissue concentrations at 4 h were analyzed. Half-lives of valproate, phenobarbital, diazepam (and metabolites), phenytoin, and levetiracetam were 2.6, 15.8, 22.3, 16.3, and 3.2 h, respectively, compared to 0.8, 7.5, 7.7, 16.0, and 1.5 h reported for adult mice. Brain-to-blood ratios were comparable with adult ratios. AEDs tested had longer half-lives and maintained therapeutic plasma concentrations longer than reported in mature mice, making clinically relevant protocols feasible.
