Body condition score and weight are effective targeted selective treatment indicators for gastrointestinal nematodes in premating ewes.
Article in The Veterinary record, 2025. 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
backgroundEwe reproductive performance is key for flock profitability but can be impacted upon by gastrointestinal nematode (GIN) infections. Farmers commonly deworm ewes pre-mating, yet concerns regarding anthelmintic resistance increase pressure to reduce wormer use.
methodsThis study retrospectively assessed pre-mating targeted selective treatment (TST) indicators in a flock of 354 ewes split into anthelmintic treatment and control groups. Conway-Maxwell-Poisson and binomial regression analyses were used to identify TST indicators associated with reproductive performance.
resultsThere was no significant difference in overall scanned litter size between treated and untreated ewes. However, ewes with a body condition score (BCS) less than 3 or a weight less than 60 kg that were not dewormed had significantly lower litter sizes (mean 1.2 and 1.41, respectively) than those treated (1.94 and 1.8, respectively) or with higher condition/weight regardless of worming status (p < 0.05). LIMITATIONS: Parasite diagnostics were not undertaken on all individual ewes, and the study assumes that differences identified in the reproductive performance of treated and untreated groups were due to GIN infection.
conclusionThese findings suggest that BCS and weight are effective indicators for implementing TST pre-mating, enabling reduced anthelmintic use without compromising reproductive outcomes.
