Multivariable negative binomial regression of P. knowlesi incidence (including population offset) in Plasmodium knowlesi study, Sabah, Malaysia, 2008–2012*

Variable IRR (95% CI) p value
% Forest remaining, ≤2 km radius
<65 Reference 0.0004
1.51 (1.42–1.99)

% Forest lost in the past 5 y, ≤2 km radius
<8 Reference <0.0001
8–14 1.68 (1.27–2.22)
2.22 (1.53–2.93)

Mean elevation per 10 m above sea level, ≤5 km radius 0.98 (0.96–0.99) 0.001

*Population was used as an offset to correct the number of infections reported for an estimate of the population size. Radius is calculated as distance from village center. IRR, incident rate ratio.
