Effect size (Hazard Ratio and 95% CI) in Discovery cohort is presented per standard deviation change in protein concentration. Proteins are grouped to TGF-β signaling, BMP signaling, and Activin signaling. Bonferroni correction for n=25 independent tests (the number of examined proteins by the study design) yielded a threshold of P < 2.0×10−3. Bonferroni correction for n=1,129 independent tests (the number of proteins on SOMAscan) yielded a threshold of P < 4.0×10−5. Red dots show proteins that were replicated and validated in other study cohorts. See Supplementary Table S2
* Proteins which were measured only in 113 out of 219 subjects in the Discovery cohort in the 1st stage of SOMAscan screening (see methods).
Anti-Muellerian hormone type-2 receptor (AMHR2) was significant (Bonferroni corrected P=0.024) in the 1st stage, but was not measured in the 2nd stage due to technical reasons.
