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

Anxiety is a multidimensional behavioral disorder widely studied in neuroscience due to the involvement of specific neural circuits. Although benzodiazepines are commonly used, their side effects drive the search for new therapeutic alternatives. This study investigated the anxiolytic effects of the indole alkaloids isoreserpine (IRPN) and isoreserpiline (IRPL), extracted from Rauvolfia ligustrina, in adult zebrafish at doses of 4, 12, and 20 mg/kg, along with 3% DMSO and diazepam (4 mg/kg) as controls. Toxicity, locomotor activity, anxiolytic effects, and serotonergic involvement were assessed. Interactions with the 5-HT3AR receptor were analyzed through molecular docking, and pharmacokinetic properties were evaluated using DMPK. The samples showed no toxicity (LD
