Figure.

Total mortality, coronary heart disease (CHD) mortality, CHD events, and atrial fibrillation in endogenous subclinical hyperthyroidism vs euthyroidism. Age and sex-adjusted hazard ratios (HRs) and their 95% confidence intervals (CIs) are represented by squares or diamonds, those to the right of the solid line indicate increased risk. The sizes of data markers are proportional to the inverse of the variance of the HRs. *Forty-one participants were excluded from the analyses of CHD mortality because of missing cause of death. †The Birmingham Study,⁶ HUNT (Nord-Trøndelag Health Study),²⁷ SHIP (Study of Health in Pomerania),³⁹ and Brazilian Thyroid Study⁴⁰ were not included because follow-up data were only available for death. EPIC indicates European Prospective Investigation of Cancer.
