Height was also measured in 1032 (90.8%) children in March–April 2010. There was no differential follow-up by sex or treatment group at any of the Phase 3 trial visits or at the follow-up visit in March–April 2010, or for collection of birth weight. WAZ for each child were calculated at each Lapatinib purchase of the five visits, and HAZ and WHZ were calculated for the March–April 2010 visit. No statistically significant differences in WAZ, HAZ or WHZ were observed between treatment groups at the March–April 2010 follow-up visit. WAZ at this visit had a mean of −1.58 (95%

CI −1.66 to −1.51) in the vaccine group and −1.58 (95% CI −1.66 to −1.51) in the placebo group (p = 0.9163). HAZ at this visit had a mean of −1.93 (95% CI −2.01 to −1.85) in the vaccine group and

−1.88 (95% CI −1.96 to −1.79) in the placebo group (p = 0.3970). WHZ at this visit had a mean of −0.73 (95% CI −0.81 to −0.65) in the vaccine group and −0.76 (95% CI −0.84 to −0.69) in the placebo group (p = 0.5326). Fig. 1, Fig. 2 and Fig. 3 show the distributions BI 2536 in vivo of WAZ, HAZ, and WHZ in each treatment group. In examining the most severely malnourished children, defined as those who were −3 Z scores or less by WAZ (underweight), we observed 20 (out of 1136) at the first study vaccine dose, 19 (out of 887) at the second dose, 16 (out of 860) at the third dose, 42 (out of 1125) at the March 2009 visit, and 57 (out of 1033) at the March–April 2010 visit. The March 2009 visit was the only visit at which there was a noteworthy difference in the through number of severely malnourished children in the vaccine (15 children) versus placebo (27 children) group, with an odds ratio of 0.54 (95% CI 0.27–1.08) for vaccine recipients (p = 0.0599). This effect was no longer apparent at the March–April 2010 visit. For severe malnutrition defined as −3 Z scores or less by HAZ (stunting, only measured at March–April 2010 visit), we observed 58 in the vaccine group and 57 in the placebo group ( Table 2). Children were observed to have increasing odds of being severely malnourished if they were severely malnourished at a prior study visit. Children were

five times more likely to be severely underweight at the March–April 2010 visit if they were defined as having a low birth weight (OR = 5.14, 95% CI 1.74–15.25, p = 0.003). Low birth weight children were also at three times greater odds of being severely stunted at the March–April 2010 visit (OR = 2.96, 95% CI 1.38–6.34, p = 0.005). Infants defined as severely malnourished by WAZ at the first study vaccine dose were at four times higher odds of being severely stunted at the March–April 2010 follow-up visit (OR = 3.96, 95% CI 1.49–10.51, p = 0.006). There was no evidence for a difference in growth patterns between vaccine and placebo recipients by t-test or longitudinal analysis.
