Bland–Altman-based plots showing agreement between CDC-LT and indoor HLC (upper panels) and between HDT and outdoor HLC (lower panels). The solid lines (—) represent the mean ratios of geometric mean catches for the village-month for CDC-LT or HDT compared to HLC (the overall bias). The ratios of geometric catches per village-month were obtained by exponentiating the differences of the logarithms of arithmetic means per village-month between CDC-LT or HDT and HLC i.e. (exp (log (CDC-LT + 1)—log (Indoor HLC + 1)) for CDC-LT to indoor HLC or exp (log (HDT + 1)—log (Outdoor HLC + 1)) for HDT to outdoor HLC). The regression equations used to estimate the overall biases are the translation algorithms that account for the density-dependence of the CDC-LT or HDT effects relative to the HLC. The dotted lines (----) represent the 95% limits of agreement, in which 95% of the ratios were expected to lie
