Models assessing multiplicative interactions for odds of POMS (sensitivity analysis: using inverse probability weighting)

Model	Interaction term	Exposure to toxic chemical, OR (95% CI)	Secondary risk factors (DRB1*15 +, A*2 -, IL-6 GG+, BCL2 GG+, NFKB1 GG+), OR (95% CI)	Interaction, OR (95% CI)
1	Exposure to Insect repellent for ticks or mosquitos X DRB1*15	1.75 (1.15–2.65)*	2.94 (1.69–5.11)***	0.60 (0.30–1.22)
2	Exposure to Insect repellent for ticks or mosquitos X A*02	1.48 (0.84–2.62)	1.24 (0.71–2.17)	1.02 (0.50–2.09)
3	Exposure to weed control products X DRB1*15	2.50 (1.61–3.88)***	2.67 (1.77–4.02)***	0.72 (0.35–1.49)

6	Exposure to weed control products X BCL2 GG +	3.40 (1.75–6.62)***	1.24 (0.78–1.97)	0.56 (0.25–1.24)
7	Exposure to weed control products X NFKB1 GG +	1.92 (1.21–3.05)	0.75 (0.46–1.20)	2.26 (0.99–5.17)
8	Exposure to plant/tree insect or disease control products X DRB1*15	4.06 (2.08–7.93)***	2.36 (1.65–3.36)***	0.55 (0.19–1.60)
