Fig. 4

‘Equivalent uncertainty’ zones (5 × 5 km grid resolution). Prevalence is displayed on the 0–1 colour scale. Zones of ‘equivalent uncertainty’ are shown superimposed (dark grey) onto the prevalence resistance map of Fig. 1b. The three highest ranked percentiles (in 20 % bands) associated with the uncertainty map of Fig. 3a are shown. Each zone would represent a priority region to be targeted with second phase sampling aimed at improving the accuracy of the current resistance map: a top percentile (0–20 %), b second percentile (21–40 %), c third percentile (41–60 %). d Top percentile (0–20 %) with the spatial constraint imposed (light grey) to exclude those regions where transmission is unstable (as defined by MAP, 2010 [21])
