“…Whilst Sherrill, Lebowitz, Knudson, and Burrows (1993) and Janson-Bjerklie, Carrieri, and Hudes (1986) reported gender differences in disease symptoms, Van den Boom et al (1998) found no such differences between COPD patients who did or did not consult their general practitioners concerning respiratory symptoms. Moreover, gender differences were also found in married people (Mookherjee, 1997), homeless people (Ritchey, La Gory, & Mullis, 1991) and with regard to sensitive cough reflex, in healthy subjects (Dicpinigaitis & Rauf, 1998).…”
