Notes: LCA adjust for clustering and weighting. N=6605. Underlining indicates that the probability is better for health compared to the overall mean (greater or less than the 95% confidence interval around the overall mean); shading indicates that the probability is significantly worse for health. Bold (better for health) or italics (worse for health) represent greatest difference from mean.
