FIG 3:

Risk factors potentially associated with drug failure. This figure describes the relative frequency of the person in charge of drenching (veterinarian (1 per cent of responders), horse owner (59 per cent of responders) or both (40 per cent of responders)) on (a). The frequency of some potential risk factor in the use of anthelmintic compounds is also illustrated through a stacked bar plot about the awareness of off-label use (b) and the distribution of the estimated proportion of clients (given by responders; listed on the x-axis as a percentage value) buying their anthelmintic drugs from the internet (c). In each case, plots are based on a total count of 91 responders
