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
Gastrointestinal parasitism severely impacts small ruminant production in tropical regions. This study investigated prevalence, risk factors, infection intensity, and co-infection patterns in 1013 goats across five districts in Southern India, while evaluating the field applicability of FAMACHA© scoring as a practical clinical indicator. Overall parasite prevalence was 80.4%, dominated by strongyle nematodes (84.9% of infected animals) and Eimeria spp. (57.3%), with 71.5% mixed infections. Multivariable logistic regression identified breed, sex, season, age, and deworming history as independent predictors of infection. Molai Adu goats exhibited the highest risk (Adj OR = 2.65, p < 0.001), females exhibited a 2.09-fold higher risk of infection compared to males (p < 0.001), and animals > 18 months had substantially lower risk (Adj OR = 0.39, p < 0.001). Non-dewormed animals had 2.79 times higher odds of infection (p < 0.001) with markedly greater mean EPG (718.3 vs. 329.2). Crucially, FAMACHA© scores strongly correlated with infection intensity (r = 0.615, p < 0.001), with geometric mean EPG increasing 15-fold from non-anemic animals (32 eggs/gram) to severely anemic animals (484 eggs/gram) (p < 0.001 for all pairwise comparisons). This dose-response relationship strongly supports the use of FAMACHA© as a practical, non-invasive field-based indicator of clinically relevant gastrointestinal nematode infection. Strategic interventions combining seasonal deworming, targeted treatment of vulnerable groups, and FAMACHA©-guided selective deworming are essential for sustainable parasite control in tropical goat systems.
