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

Characterizing drug distribution to target organs is of central importance to drug discovery, especially for compounds intended to reach the central nervous system (CNS). However, the current benchmark standard measurements, based on tissue homogenate, provide limited spatial and temporal resolution. Here, we use real-time electrochemical aptamer-based (E-AB) monitoring to determine drug concentrations across specific brain regions, blood, and liver of rats after intravenous dosing. Using vancomycin and tobramycin as models, we reveal significant regional differences in brain pharmacokinetics. Vancomycin shows distinct kinetics across cortex, hippocampus, and thalamus, crossing the blood-brain barrier (BBB) but showing limited transport across the blood-cerebrospinal fluid barrier (BCSFB). Tobramycin, despite its smaller size, fails to cross either barrier. Vancomycin's liver distribution is delayed and limited, resembling its brain kinetics more than blood. These findings challenge assumptions of uniform CNS drug distribution and fast liver uptake, highlighting the need for spatially and temporally resolved pharmacokinetic assessments. Our approach enables high-resolution, in vivo profiling of drug absorption, distribution, and clearance, offering a powerful tool to inform dosing strategies and improve translational outcomes.
