Multilevel mixed-effects generalized linear model for weighted-average change in WRI score (projected water stress in 2040) of total supply and imports for cereals, fruits, vegetables and pulses.

	Total supply		Imports
Food group	Average change in WRI score1 per year	95% CIs	Average change in WRI score1 per year	95% CIs
Cereals	0.015	0.012, 0.018**	0.013	0.005, 0.021*
Fruits	0.024	0.021, 0.027**	−0.014	−0.022, −0.005*
Vegetables	−0.013	−0.019, −0.008**	−0.025	−0.030, −0.020**
Pulses	0.008	−0.005, 0.022	−0.041	−0.060, −0.023**

*p < 0.01, ^**p < 0.001; ¹ WRI scores range from 1 to 5, whereby the higher the score, the more water stressed a country is projected to be.
