Table 2 Cumulative tick burden, prevalence and median tick burden in ruminants on livestock farms in the context of agro-ecological zones and districts of Punjab Province, Pakistan. Prevalence (OR = 0.60, 95% CI: 0.37–0.98, P = 0.037) and tick burden (W = 10,650, P = 0.002) were significantly different between the agro-ecological zones

From: Distribution of ticks infesting ruminants and risk factors associated with high tick prevalence in livestock farms in the semi-arid and arid agro-ecological zones of Pakistan
