Comparative Evaluation of Two In Vitro Tests for Detection of Ivermectin Resistance in Haemonchus contortus of Small Ruminants in Uttar Pradesh, India.

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
purposeResistance against ivermectin in India has been detected solely implementing in vivo tests and there is no published report of resistance employing in vitro methods. The present study was carried out to study ivermectin resistance in H. contortus of small ruminants by two in vitro tests and to determine their efficacy in effectively detecting ivermectin resistance in the field isolates.
methodsThe present study was carried out in the small ruminant farms of the western region of Uttar Pradesh, India. Faecal samples with high egg per gram of faeces for H. contortus were selected. Two in vitro tests namely Micro agar larval development test and larval development assay were performed for assessing ivermectin resistance in field isolates of H. contortus by subjecting the eggs to different concentrations of ivermectin aglycone.
resultsThe results of the two in vitro tests implicated towards the susceptibility of H. contortus isolates in the area under study. The standard deviations of the two tests was compared and was found to be statistically non-significant.
conclusionIt can be said that both in vitro tests are reliable for detecting resistance against different anthelmintics including ivermectin.
