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
purposeThis study explores the detailed effects and mechanisms of Zhi Zhu Ma Ren Pill (ZZMRP) on constipation.
methodsMouse constipation was induced by using loperamide (Lop). The effects and mechanisms of ZZMRP on constipation were addressed by various methods including charcoal meals, hematoxylin and eosin (H&E) staining, immunohistochemistry, enzyme-linked immunosorbent assay (ELISA), terminal deoxynucleotidyl transferase deoxyuridine triphosphate (dUTP) nick end labelling (TUNEL), transmission electron microscopy, and western blot experiments.
resultsLop-treated mice exhibited delayed transit and reduced ink progradation rates after charcoal meal administration. H&E staining confirmed severe pathologic symptoms in these mice. Additionally, a decline in interstitial Cajal cells (ICCs) was observed in Lop-treated mice, accompanied by reduced concentrations of 5-hydroxytryptamine (5-HT), acetylcholinesterase (AchE), substance P (SP), and vasoactive intestinal peptide (VIP), coupled with an elevated concentration of nitric oxide synthase (NOS). However, ZZMRP treatment markedly ameliorated these changes. In addition, ZZMRP introduction significantly reversed the Lop-induced enhancement in apoptosis rate, endoplasmic reticulum (ER) stress, and levels of proapoptotic proteins and ER stress proteins, and the decrease in the expression of antiapoptotic proteins. These effects were further confirmed with the use of 4-phenylbutyrate (4-PBA), which also reversed the changes in apoptosis rate and protein levels.
conclusionZZMRP alleviates constipation primarily through modulating ER stress-mediated apoptosis in Lop-treated mice, suggesting its use as a therapeutic agent for constipation.
