  1. aThe mean values for the variables are reported with chi-square tests for the difference between the local and improved categories. Significance: ***P < 0.0001; **P < 0.001; *P < 0.01; bMultiple responses for households listing up to three factors (1 if a major reason, 0 if not); c1 = Good, 2 = Ok, 3 = Not so good; d1 < 100 days, 2 = 100 to 120, 3 > 120; e1 = Very good, 2 = Good, 3 = Not good.
