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
objectiveAcyclovir is an antiviral drug that is used to treat herpes virus infections and acts by inhibiting viral DNA synthesis. While antiviral drugs are designed to inhibit viral replication, some have been found to have immunomodulatory effects beyond their direct antiviral action. Acyclovir has been documented to induce cytotoxicity and DNA mutation. Cytotoxic agents are well-documented to damage male gonadal functions. Therefore, it has become imperative to examine the effects of acyclovir on male reproductive physiology.
methodsEighteen adult male Wistar rats were randomly grouped into three groups: control (distilled water), low-dose (10 mg/kg acyclovir), and high-dose (40 mg/kg acyclovir). After 21 days of oral treatment, serum, testicular homogenate, and epididymal sperm suspension were collected and analyzed. Serum and testicular oxidative stress markers (SOD, MDA, GPx, and CAT), hypothalamic-pituitary-gonadal hormones (GnRH, LH, FSH, and testosterone), sperm parameters, and testicular histoarchitecture were examined. In addition, inflammatory cytokines (IL-1β, IL-6, IL-10, TNF-α) and lactate dehydrogenase enzymes were evaluated from the serum.
resultsAcyclovir (40 mg/kg) caused a significant increase in serum inflammatory cytokines (TNF-α, IL-6), LDH, and MDA, while the testicular and serum antioxidant enzymes were reduced when compared with controls. Acyclovir (40 mg/kg) also decreased serum GnRH, LH, FSH, and testosterone levels, as well as testicular testosterone, and negatively affected sperm count, sperm motility, and sperm morphology. Histopathological examination showed that acyclovir caused edematous seminiferous tubules with degenerated spermatogenic cells and scanty sperm cells.
conclusionsAcyclovir induced testicular damage by promoting inflammatory response, oxidative damage, and endocrine disruption.
