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
Chronic stress is a major contributor to male reproductive dysfunction leading to testicular damage and impaired spermatogenesis. This study investigates the protective effects of β-sitosterol, a phytosterol with known antioxidant properties, against CUS-induced testicular damage in rats. Male Wistar rats were divided into Control, Chronic Unpredictable Stress (CUS), and CUS + β-sitosterol. The CUS and CUS + β-sitosterol groups were exposed to random stressors for eight weeks. β-Sitosterol was administered orally at a dose of 20 mg/kg for three weeks, starting from the fifth week of CUS induction. Behavioral tests like EPMT and NSFT were conducted to confirm CUS induction, after which serum, testis, and epididymis samples were collected for analysis. β-sitosterol significantly increased testis and epididymis weight, along with sperm counts in CUS rats. Histological analysis revealed restoration of testicular cellular structure, as indicated by an improved Johnsen's index scores. Additionally, β-sitosterol restored antioxidant levels and oxidative stress parameters in testicular tissue. TEM showed germ cell integrity and restored basement membrane structure in the CUS + β-sitosterol group. In silico analysis indicated strong interactions of β-sitosterol with FNDC5, P450scc, and 3β-HSD proteins involved in steroidogenesis. Immunohistochemistry confirmed an increased expression of FNDC5 in the CUS + β-sitosterol group, β-sitosterol ameliorates CUS-induced testicular damage and improves sperm count, highlighting its potential as a dietary intervention for stress-related male infertility. Further preclinical and clinical studies are warranted to explore its therapeutic potential.
