Table 2 Correlation and regression analysis of log-transformed indoor human landing (HLC) and light trap (LTC) collections of Anopheles gambiae s.l. on Bioko Island, 2009. The correlation coefficients show the relationship between log(LTC + 1) and log(HLC + 1)). The regression slopes are from regressing relative sampling efficiencies (log(LTC + 1)-log(HLC + 1)) on average abundance ([log(LTC + 1) + log(HLC + 1)]/2)

From: Light traps fail to estimate reliable malaria mosquito biting rates on Bioko Island, Equatorial Guinea
