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
BACKGROUND This study examined the effects of khat extract on the proinflammatory cytokines, liver, and kidneys of rats. Unlike previous research that focused on broad immune markers and general effects, this study investigated specific proinflammatory cytokines (IL-1ß, IL-2, IL-4, IL-6, and TNF-alpha) and considered gender differences in the immune response. Fresh khat plants and nontoxic doses were used to obtain clear observations relevant to human health. MATERIAL AND METHODS Extracts were prepared from young shoots of khat plants and fresh leaves. 150-gram male and female rats were randomly divided into 8 groups (5 rats per group). Six groups received the extract orally for 8 weeks at doses of 100, 300, and 500 mg/kg/day. Blood samples were collected after 56 days and assayed for cytokines using ELISA, while liver enzymes and kidney markers were assayed using kinetics and colorimetric methods. RESULTS Khat extract increased the levels of most cytokines, with higher doses causing greater increase. This effect was consistent across sexes for some cytokines (IL-1ß, IL-2), but not others (IL-4, IL-6, TNF-alpha), where sex played a role at specific doses. Various doses of the extract influenced glucose levels in both male and female rats. In addition, liver enzyme markers showed some variations. CONCLUSIONS This study, with its intriguing findings, illuminates the complex effects of khat on various systems. Variations in AST and ALT levels in the liver support earlier hepatotoxicity research and suggest possible khat-induced damage. This study revealed consistently increased levels of all cytokines as the dose of khat extract increased.
