Data are presented as OR (95% confidence interval), unless otherwise indicated. NRL: natural rubber latex; NE: could not be estimated due to small numbers. #: adjusted for sex, age, education, parental atopy or asthma, smoking status, second-hand smoke exposure at work and/or at home, and work stress; ¶: factory workers formed the reference category (OR = 1); +: adjusted for NRL exposure; §: adjusted for milk powder exposure; ƒ: adjusted for exposure to irritants; ##: adjusted for exposure to sensitisers.
