  1. * Numbers in each of the five symptom categories add to 858 the total number in the cohort. Numbers given are relevant for unadjusted hazard ratios. Numbers in the sample for each of the adjusted analyses varies only slightly since there was little missing data for the factors we have adjusted for (as can be seen from tables 1 and 2).
  2. 1 Adjusted for gender, housing tenure and smoking status
  3. 2 Adjusted for gender, housing tenure, smoking status and the presence of a respiratory or cardiovascular condition
  4. 3 Adjusted for gender, housing tenure, smoking status, the presence of a respiratory or cardiovascular condition and the number of symptoms present in the last month
