Figure 2. Hazard Ratios (HRs) and corresponding 95% confidence intervals (95% CIs) for the association between z-score of body height at the entry to adulthood as a cubic spline with four knots and dementia.

A z-score of 0 is the reference value. Stratified by birth cohort and adjusted for conscript board district, educational level and intelligence test scores. Age included as underlying scale of the model. The analysis included the total population of men. Identify cohort-specific values of one z-score in Supplementary file 2.

Figure 2—figure supplement 1. Distribution of mean numeric difference in body height in cm between brothers (A) and twins (B).

Note: to hide micro data, the value 26 includes all values above for brother and the value 17 includes all values above for twins. In cases where there were more than two brothers with a shared mother, the difference in body height between all brothers were included. For example, for a groups of three brothers, the differences between brother one and two, brother one and three, and brother two and three, respectively, were included.
