Kramer 2000a found a small and
nonsignificant reduction in risk of 2 or
more respiratory tract infections (upper
and lower combined) RR 0.90 (95% CI
0.79 -1.03) (outcome 53). The
combined crude results of Oddy
1999and Kramer 2000a show a
substantial and statistically significant
reduction in risk for hospitalization for
respiratory tract infection pooled RR
0.75 (95% CI 0.60 -0.94), but the crude
risk reduction in Kramer 2000a was
nearly abolished and became
statistically nonsignificant in a
multivariate mixed model controlling
for geographic region, urban vs rural
location, maternal education and
cigarette smoking, and number of
siblings in the household adjusted OR
