Subgroup analysis for the association of SUA and OP or osteopenia. Subgroup analysis of the association between SUA and OP or osteopenia, stratified by age, sex, BMI, hypertension, stroke, CHD, DM, hyperlipidemia, and fatty liver. Each square in the forest plot represents an estimated Odds Ratio (OR) for a specific subgroup. The size of the square is usually proportional to the statistical weight or sample size of that estimate. “P for interaction” tests whether there is any interaction between the subgroups.
