Prevalence, morphology and associated risk factors for cystic ovaries in companion guinea pigs (Cavia porcellus).
Article in The Veterinary record, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundOvarian cysts are the most common reproductive pathology in guinea pigs, yet their prevalence and associated risk factors in clinically healthy individuals remain poorly understood. This study investigated the prevalence, size and morphology of ultrasonographically detectable ovarian cysts in guinea pigs and their associated risk factors.
methodsA total of 221 female guinea pigs from private households and breeding collections underwent ultrasound examination to identify ovarian cysts and determine their size and morphology. Each animal's age, breed, parity and body condition were also recorded.
resultsThe overall prevalence of ovarian cysts was 41.6%, increasing from 25.4% in animals less than 1 year old to 68.2% in those over 3 years old. Cyst size increased significantly with age (0.33 mm/month). Each increase in parity was associated with a 2.15 mm decrease in cyst size. Guinea pigs from breeders had a significantly lower prevalence of polycystic ovaries compared to privately owned individuals. Breed and body condition did not significantly affect cyst prevalence. LIMITATIONS: Histopathological cyst type and concurrent uterine disease were not examined.
conclusionAge was the primary risk factor for ovarian cyst development in this population of guinea pigs, while an increase in parity decreased cyst size. Further research is needed to explore additional risk factors and establish clinically relevant cyst size thresholds.
