Fig. 1From: A new strategy for enhancing imputation quality of rare variants from next-generation sequencing data via combining SNP and exome chip dataScatter plot of estimated r2 against dosage r2 by MAF bins. Estimated r2 was plotted against dosage r2 by MAF bins (a) MAF ≥ 5 %, (b) MAF = 1–5 %, (c) MAF = 0.5–1 %, (d) MAF < 0.5 %, (e) MAF = 0.3–0.5 %, and (f) MAF < 0.3 %.
