Adjusted differences and 95% confidence intervals for mean scores on the illness management index (IMI) by scores on the Raven’s Progressive Matrices, stratified by years of schooling for 466 rural Guatemalan women participating in a longitudinal study between 1996–1999.1
| Scores on the Raven’s Progressive Matrices | Years of Schooling | ||
|---|---|---|---|
| < 1 year (n=85) | 1–6 years (n=324) | >6 years (n=51) | |
| Missing | −1.24 (−2.26, −0.21) | 0.33 (−0.12, 0.78) | 0.11 (−0.26, 0.48) |
| < 13 | −1.18 (−2.20, −0.17) | 0.13 (−0.25, 0.50) | −0.22 (−0.65, 0.21) |
| 13 – 17 | −0.90 (−1.91, 0.10) | 0.11 (−0.23, 0.45) | −0.35 (−0.71, 0.01) |

1
Adjusted mean differences estimated from mixed effects models with random intercept; 95% confidence limits were calculated using robust variance estimates.
2
Model adjusted for maternal age, work, marital status, maternal academic skills scores, household SES score, hygiene index score, community of residence, infant sex and age, and duration and severity of diarrheal episode.
