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

Currently, mechanism-based inactivators (MBIs) are the only available therapeutic option to target γ-aminobutyric acid aminotransferase (GABA-AT). However, off-target activity against homologous enzymes is a well-recognized challenge for the clinical use of MBIs. For example, CPP-115, an MBI of GABA-AT that completed a Phase I clinical trial, also inactivates ornithine aminotransferase (OAT). Here, we present a comprehensive investigation of an OAT-specific inactivation mechanism for CPP-115 by integrating biochemical experiments, X-ray crystallography, and computational simulations. Unlike in GABA-AT, where CPP-115 forms a noncovalent tight-binding adduct only, a covalent adduct was additionally observed with human OAT (
