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
backgroundTicks and tick-borne diseases are major constraints to cattle productivity in sub-Saharan Africa. This study assessed the epidemiology and host-level determinants of tick infestation in communal cattle systems in South Africa.
methodsThis cross-sectional study examined 787 cattle across 17 villages. Animal-level data included sex, breed (Nguni, Drakensberg, Bonsmara, Brahman, Hereford, Simmentaler, and crossbreeds), age, and body condition score. Tick burden was quantified on six anatomical sites, and whole-body burden was estimated from one-sided counts.
resultsTick burden was heterogeneously distributed across anatomical predilection sites, with the ears (mean = 50.7 ticks), lower perineum (mean = 44.4 ticks), and upper perineum (mean = 34.2 ticks) exhibiting the highest infestation intensities. Older cattle (> 8 years; IRR = 1.58, 95% CI: 1.39-1.79) and adult cattle (> 2-8 years; IRR = 1.43, 95% CI: 1.26-1.63) harboured significantly more ticks than young cattle (≤ 2 years). Indigenous and crossbred cattle exhibited lower tick burdens than exotic breeds, although breed was not a significant predictor of tick burden after adjustment. Multilevel negative binomial modelling confirmed age and body condition score as independent predictors of total tick burden, while accounting for farm-level clustering. Sex was not a significant predictor, and farm-level clustering accounted for 47% of variance in tick burden. Indigenous and crossbred cattle exhibited lower tick loads than exotic breeds.
conclusionTick infestation is prevalent in communal cattle systems in South Africa, particularly in the ears and perianal regions of exotic cattle breeds. These findings provide evidence-based epidemiological data on aggregate tick burden and host-level predictors to inform communal livestock health planning and guide future species-resolved investigations.
