Linear mixed regression models for individual observations of skin exposure for body parts with >50% detectable samples: logged dermal exposures (μg/cm²) as response variable (Y), task and subject included as random effects (model A); with task and subject included as random effect and DREAM estimates as fixed effect (model B); and with task and subject included as random effect and detailed DREAM_DET estimates as fixed effect (model C)
