Urinary 2,5-hexanedione excretion in cryptogenic polyneuropathy compared to the general Swedish population

Table 2 Exposure variables included in different linear regression models with respect to urinary 2,5-HD levels

Occupational exposure		Life style	Solvent exposure
Model 1 Men	Model 1 Women	Model 2	Model 3
Sulphur dioxide	Lead	Born in Sweden	2,5-hexanedione solvents¹
Xylene*	Nitrous oxide*	Current smoking	Nitrous oxide occupationally*^{for women}
Methyl ethyl ketone	Insecticides	Fruit several times/week	Solvents in leisure time
Herbicides		Vegetables several times/week	General anaesthesia and surgery*^{for men}
Solvents leisure time		Meat several times/week
		Fish several times/week
		Alcohol ≥2 times/month*^{for men}

¹Methyl-n-buthyl ketone, petrol, Stoddard solvent, jet fuel, n-hexane. * p<0.05. Xylene, alcohol consumption and anaesthesia was associated with lower 2,5-HD urinary excretion in men. Nitrous oxide exposure was associated with higher 2,5-HD urinary excretion in women.
In all models case/referent status and year of birth was included and analysed separately by sex.
