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.
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
backgroundRauvolfia vomitoria (R. vomitoria) is a plant of economic importance due to its diverse ethnomedicinal properties, including the anticonvulsant effect. In this study, we studied the antiseizure and neuroprotective potentials of R. vomitoria extracts against pentylenetetrazol (PTZ)-induced kindling.
methodsTwenty-five adult Swiss mice (25-30 g) were assigned to five groups (n = 5): control group, PTZ treatment group, and PTZ treatment after receiving oral R. vomitoria crude extract (100 mg/kg), R. vomitoria phenol extract (50 mg/kg) or sodium valproate (15 mg/kg) every 48 h for 28 days. Seizure scores, cognitive behavioral tests including novel object test, Y-maze test, and the elevated plus maze test, as well as brain neurochemicals and histomorphology studies, were performed.
resultsCompared with the control group, the PTZ group showed comparable body weight and durations in closed and open arms (P > 0.05), but preference for familiar objects, significant (P < 0.05) spontaneous alternation, increased monoamine oxidase activity and nitric oxide level, and Nissl chromatolysis in the temporal lobe structures including the cortex, hippocampus, and amygdala. R. vomitoria phenol extract pretreatment significantly (P < 0.05) reduced seizures, prevented adverse cognitive behaviors, decreased the nitric oxide level, and reduced the temporal lobe Nissl chromatolysis compared with the R. vomitoria crude extract pretreatment group and the sodium valproate pretreatment groups.
conclusionsThus, R. vomitoria phenol extract showed promising results against seizures and potential for general brain protection, suggesting that the anticonvulsant property of R. vomitoria may be attributed to its phenol constituent. More studies are needed to delineate the mechanisms of its action.
