Estimated differences and 95% confidence intervals for systolic and diastolic blood pressure and prevalence of hypertension associated with longer school term length and school term attendance, by sex and race, NHANES I & II^a,^b.

<p>^a The model includes linear and quadratic terms for age centered at the sample mean, indicator variable for NHANES sample, indicator variables for birth year and indicator variables for state of birth.</p><p>^b Estimates from models with continuous blood pressure outcomes can be interpreted as difference in mmg/Hg associated with 10% change in school term length. Estimates from models for hypertension can be interpreted as the difference in percentage points in the probability of hypertension associated with 10% change in school term length.</p><p>Estimated differences and 95% confidence intervals for systolic and diastolic blood pressure and prevalence of hypertension associated with longer school term length and school term attendance, by sex and race, NHANES I & II<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129673#t002fn001" target="_blank">^a</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129673#t002fn002" target="_blank">^b</a>.
