  1. * The percentage of probes included in non-singleton clusters. In the model LDpred2, CMR blocks, no singletons, this means that only 18% of the probes were used in the analysis, since singleton clusters were discarded
  2. ** For detailed results, see Appendix II
  3. CMR: co-methylated region, TAD: topologically associating domain
