The effect of cooling interventions among agricultural workers on the self-report of one or more heat-related symptoms during the workday, n=74

	Unadjusted	Adjusted for single covariate
		BMI	Heat Index Max	Years worked in agriculture	Hours worked per day	Moderate-vigorous activity
Cooling Intervention (ref=No intervention)	OR [90%CI]
Bandana	0.4 [0.2, 1.3]	0.4 [0.2,1.4]	0.4 [0.1, 1.5]	0.4 [0.1, 1.4]	0.4 [0.1, 1.2]	0.7 [0.2, 2.4]
Vest	0.6 [0.2, 1.8]	0.5 [0.2, 1.8]	0.5 [0.2, 1.7]	0.5 [0.2, 1.7]	0.4 [0.1, 1.5]	0.8 [0.2, 2.8]
Combination	0.2 [0.1, 0.8]	0.2 [0.1, 0.7]	0.3 [0.1, 1.0]	0.2 [0.1, 0.8]	0.2 [0.1, 0.7]	0.3 [0.1, 1.2]

Note. OR= odds ratio; CI= confidence interval. The outcome is “during the workday, participant self-reported one or more heatrelated symptom, yes/no”. Odds ratios <1 suggest a protective effect of the intervention.
