  1. The difference between the mean, number or percentage of low red cell folates in 1996 and 1997 is significant (P < 0.01), between those of 1997 and 1998 is also significant (P < 0.001), but the differences between those of 1998, 1999-2001 and 2002-2004 are not significant, based on Chi square calculation and t-test(By January first 1998 almost all of grain products in Canada were fortified with folic acid).
