Figure 2From: Evaluation of gene-based association tests for analyzing rare variants using Genetic Analysis Workshop 18 dataReceiver operating characteristic curve examining the relationship between power and type I error for the 7 tests. (A) BTD.(B) MAP4 . The phenotype is systolic blood pressure (SBP). For the MAP4 gene, 4 of the 8 rare variants have a causal effect on SBP; in total, they explain 5.8% of variation in SBP.Back to article page
