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
backgroundStrongyle-type gastrointestinal nematodes are among the most important parasitic infections affecting sheep production because of the health and economic losses they cause.
aimThe aim of this study was to determine the positivity, parasite burden, and factors associated with positivity to strongyle-type gastrointestinal nematode eggs in sheep from Guanujo parish, Ecuador.
methodsA quantitative, descriptive, cross-sectional study was conducted between November 2025 and March 2026. Seventy fecal samples were collected individually via rectal sampling from sheep randomly selected within 14 participating farms. The samples were analyzed using coproparasitological techniques with the modified McMaster method to quantify eggs per gram of feces (EPG). Subsequently, univariate analysis and multivariable logistic regression were performed to identify factors associated with positivity for strongyle-type gastrointestinal nematode eggs.
resultsThe overall positivity was 54.3% (38/70), with a mean parasite burden of 1150 EPG. Mild and moderate infections predominated, although severe infections were also detected. After multivariable adjustment, younger age was consistently associated with positivity. High stocking density was associated with positivity in the primary model, although this association was less stable in the mixed-effects sensitivity analysis. Sheep younger than 12 months showed higher odds of positivity than adults (adjusted OR = 8.75; 95% CI: 3.42-22.38;
conclusionsYounger age was the most consistent factor associated with strongyle-type gastrointestinal nematode egg positivity. High stocking density showed higher odds of positivity in the primary analysis, but this association was not statistically significant in the mixed-effects sensitivity analysis and should therefore be interpreted cautiously.
