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

Chalcones represent a privileged scaffold in medicinal chemistry, with pyranochalcones, featuring an additional chromane-like ring, identified as neurogenic and neuroprotective. Reporter gene assays, often used to study these and other effects, can produce false positives due to firefly luciferase stabilisation by inhibitors. The present study demonstrates that pyranochalcones inhibit firefly luciferase activity, with inhibition levels ranging from none to 100% and IC
