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

Herein, we describe the optimization of a linked enzyme assay suitable for high-throughput screening of decarboxylases, a target family whose activity has historically been difficult to quantify. Our approach uses a commercially available bicarbonate detection reagent to measure decarboxylase activity. The assay is performed in a fully enclosed automated screening system under inert nitrogen atmosphere to minimize perturbation by exogenous CO2. Receiver operating characteristic (ROC) analysis following a pilot screen of a small library of approximately 3,600 unique molecules for inhibitors of Trypanosoma brucei ornithine decarboxylase quantitatively demonstrates that the assay has excellent discriminatory power (area under the curve = 0.90 with 95% confidence interval between 0.82 and 0.97).
