Progression of deltamethrin resistance in Rhipicephalus microplus populations on communal farms of South Africa.

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
This study was conducted to assess the progression of deltamethrin resistance in Rhipicephalus (B.) microplus populations over a 5-year period, from 2019 to 2023, on selected communal farms in the Eastern Cape Province, South Africa. Ticks were collected from three communal farms with a documented history of deltamethrin resistance in R. (B.) microplus populations in 2019. The sampled tick populations were tested for resistance using the adult immersion test (AIT). The data generated from the AIT indicated deltamethrin resistance, with oviposition inhibition percentages ≤ 95% at both the manufacturer's recommended dose and twice the recommended dose. These findings confirm the establishment of deltamethrin resistance in R. (B.) microplus populations on the communal farms within the KSD local municipality, following over a decade of frequent and continuous use of this acaricide. Ticks on cattle, along with their control and acaricide resistance in tick populations, pose a significant threat to livestock production on communal farms in South Africa.
