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

Phenibut is a new psychoactive substance (NPS) first synthesized in Russia in 1963 as a derivative of gamma-aminobutyric acid. Originally developed for therapeutic use, it has gained popularity for nonmedical purposes, including recreational and cognitive enhancement. In Brazil, phenibut is uncontrolled and easily purchased online. This study used wastewater-based epidemiology (WBE) to investigate phenibut use patterns in two northeastern Brazilian cities. Composite daily wastewater samples were collected from two treatment plants (WWTPs), Recife (WWTP
