566) examined mortality from heat waves in seven major Korean cities for 2000-2007 and investigated effect modification by individual characteristics and by heat wave characteristics (intensity, duration, and timing in season).
Log-transformed urine and hair levels were modeled in multivariable linear regression separately against respective exposure surrogates, and the effect modification of 13 MT SNPs on exposure was investigated.

However, further evaluation is needed in a larger sample to evaluate possible effect modification, because the risks appeared more pronounced in low social strata.
Effect modification by previous-winter mortality was not evident when we restricted deaths to cardiovascular disease outcomes in Seoul.
Heat wave mortality impacts and effect modification by heat wave characteristics were more pronounced in the Northeast and Midwest compared with the South.
To evaluate effect modification by allele-specific HFE variances, men heterozygous for both C282Y and H63D polymorphisms (known as compound heterozygote; n = 13) were excluded; thus, 619 participants were finally included in the study.
