Table 6 Description of the quantitative remotely-sensed and meteorological explicative variables associated with the adult Anopheles densities in villages

From: Utilization of combined remote sensing techniques to detect environmental variables influencing malaria vector densities in rural West Africa

Variable   Anopheles adult density* < 110 Anopheles adult density > = 110 and < 145 Anopheles adult density > = 145 and < 240 Anopheles adult density > = 240
  n observations = 55 n = 12 n = 15 n = 14 n = 14
