Proportion of farmers who detected, reported or failed to report abortions during the 2006–2011 period.
The proportion of notifying farmers (; dotted blue line and red diamond shape) was calculated as the ratio of the observed number of farmers who reported at least one abortion to the total number of farmers. The proportion of farmers who detected at least one abortion (
; grey) and the proportion of under-reporting farmers (
; light green) were estimated from the ZIP model. In 2010/2011, 60.6% [95% confidence interval: 52.4–72.2] of farmers detected at least one abortion (i.e.
;); among them, 20.0% reported at least one abortion (i.e.
). The proportion of under-reporting farmers
was estimated to be 66.4% [62.2–72.0].
