Fig. 1: Manhattan plots of the GWAS data.
From: Genome-wide association study of preterm birth and gestational age in a Japanese population
Each dot represents a variant. The x-axis represents genomic coordinates, and the y-axis represents −log10 (p value). Two colors, blue and gray, are used alternately for dots on a chromosome for easy viewing. The blue line represents the suggestive significant threshold (α) of p = 1.0 × 10−5. a Manhattan plot of genome-wide associations between variants and PTB among the Japanese population (384 cases and 644 controls). b Manhattan plot of genome-wide associations between variants and gestational age among the Japanese population.
