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

The purinergic P2X ligand-gated ion channel 7 receptor (P2X7R) plays a critical role in various inflammatory processes and other diseases. Fast determination of compounds P2X7R binding potency and discovery of a promise PET radiotracer for imaging P2X7R require a P2X7R suitable radioligand for radioactive competitive binding assay. Herein, we designed and synthesized thirteen new P2X7R ligands and determined the in vitro binding potency. The fluorescence screening assay identified the iodide compound 1c with high potency and specificity toward P2X7R with an IC
