Meta-scoring: This approach combines multiple polygenic scores for a trait/disease into a meta-score (a metaGRS or metaPGS). The method assumes that each individual polygenic score will suffer, to an extent, from regression dilution bias and, therefore, combining them into a more powerful meta-score will reduce this bias. bishop aries
