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
Introduction: Dr Iguedo Goko Cleanser® is a herbal formulation (HF) widely marketed in southern Nigeria and purported to be very efficacious for the management of various diseases including giardiasis, toilet infections, hypertension, diabetes, ulcer, impotence, low libido, low sperm count amongst others. Medicinal plants reportedly produce an array of adverse reactions capable of inducing harmful conditions, including death. Aim: This study evaluated the subchronic toxicity concern of HF on testicular function and gonadal histoarchitecture in Wistar rats. Methods: Thirty Wistar rats of both sexes were randomly divided into six groups (5/group) and were orally administered HF for 60 days. The control groups received 5 mL/kg of distilled water; the treatment groups were administered 476.24 and 158.75 mg/kg body weight of HF each for both male and female rats. Using standard procedures, semen analysis was done for all male rats. Animals were anaesthetised and sacrificed on the 62nd day; the gonads were eviscerated, weighed and fixed in 10% buffered formalin for histopathological examinations. Results: Significant (p < 0.05) increase in sperm count relative to control as well as spermatotoxic effects were observed in male rats. Histologically, the ovary presented some degrees of pathologies: cloggy appearing ovarian cortex with a display of a tumour-like cortical area, scantily displayed primordial follicles, haemorrhagic blood vessels, atretic secondary follicle, and eroding granulosa cells amongst others. Testicular histopathology showed abnormal seminiferous tubules' histoarchitecture, degenerated spermatids, distorted spermatogenic cells' orientation, and displaced spermatids into the luminal space. Conclusion: Herbal drugs are usually regarded to be completely safe due to their natural sources, however, this study discovered exposure-related toxic effects of Dr Iguedo Goko Cleanser® on testicular function and gonadal histomorphology. The findings recommend extreme caution with chronic use and avoidance whenever possible.
