Agism as explanation for sexism in provision of thrombolysis

For the remaining 880 subjects crude and age adjusted odds ratios were calculated, with logistic regression, to determine whether the hospitals' use of thrombolysis was affected by the sex, age, and smoking habits of patients, and by the interval between the onset of a patient's symptoms and admission. The confounding effect of age also explained the apparent lower use of thrombolysis in smokers but it did not affect the trend of decreasing use of thrombolysis the longer the duration of symptoms. *Reference group. [dagger]Additional adjustments for sex and smoking had no effect on odds ratios.
