Table 2 Correlation and regression analysis of log-transformed indoor (IN) and outdoor (OUT) human landing catches (HLC) with either light trap (LTC) or yeast-generated CO2-baited light trap catches (CB-LTC) of Anopheles species in Edo Kontola, Ethiopia 2014

From: Comparison of two adult mosquito sampling methods with human landing catches in south-central Ethiopia

  1. The correlation coefficients show the relationship between log(LTC + 1) and log(HLC + 1), log(CB-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) and also (log (CB-LTC + 1) − log (HLC + 1)) on average abundance ([log(CB-LTC + 1) + log(HLC + 1)]/2)
