Odor threshold least-square means and standard errors for four time points, comparing Latino farmworkers and non-farmworkers, North Carolina 2012–2014^*

	LSMEANS (SE)
	Farmworkers	Non-Farmworkers	Overall
Contact 2	7.47 (0.30)	8.27 (0.34)	7.87 (0.27)^‡
Contact 3	6.91 (0.33)	7.71 (0.37)	7.31 (0.30)^‡
Contact 4	6.82 (0.35)	7.62 (0.39)	7.22 (0.33)^‡

Overall	7.06 (0.23)^†	7.86 (0.29)^†

adjusting for baseline values of: age (3-level category), current smoking status (smoker/nonsmoker), and odor threshold at Contact 1.

^†

p-value for farmworker status difference = 0.0214

^‡

p-value for Contact difference = 0.2692
