FIGURE 4.
Forest plot of the β estimates (regression coefficients) from the meta-analysis of the association between BMI and absolute telomere length (base pairs) as outcome in the “young” pooled population (age ≥18 and ≤60 y). A random-effects model was used and adjusted for sex. Statistical heterogeneity was estimated by I2 statistics for each of the 12 meta-analyses. The shaded boxes indicate the inverse variance weighting of each estimate, and the size of the box indicates the weight. In case no shaded box is visible, the weight is very small.
