Quadratic (nonlinear) effect of households in core need on rates of salmonellosis in the NWT. The nonlinear relationship indicated that the effect of core need households on risk of salmonellosis was unlikely to remain the same as the percentage increased in communities. The rate of infection increased with each 1% increase in core need households in communities up to 42.2% after which the rate started to decrease with increasing core need.
