|---|---|---|---|---|---|---|---|---|---|---|
| Number of episodes of hospitalization per hospitalized child | FavorableUnfavorable or ambiguousNo Effect |
Two years postpartum | San Bernardino sample, hospitalized children | 28 children | Mean = 1.58 | Mean = 2.19 | Mean difference = -0.61 | HomVEE calculated = -0.14 | Statistical significance not reported | |

| Percentage of children adequately immunized | FavorableUnfavorable or ambiguousNo Effect |
Two years postpartum | San Bernardion sample | 101 mothers | Percentage = 0.77 | Mean % = 0.87 | Mean difference = -0.10 | HomVEE calculated = -0.42 | Not statistically significant, p > 0.5 | In contrast to the study-reported results, HomVEE calculations showed this difference to be statistically significant (p = 0.05).
