Table 4 Patient variables associated with physician's global estimate of disease severity †

From: Physician-estimated disease severity in patients with chronic heart or lung disease: a cross-sectional analysis

  Physician' Estimate of Disease Severity (Odds Ratio) ‡
Patient Variable Beta Much Better Somewhat Better Somewhat Worse Much Worse
   (n = 108) (n = 385) (n = 400) (n = 121)
Increases physician's severity estimate
Age (older) .173 0.950 *** 0.980 * 1.005 1.040*

Long-term Smoker (≥ 20 pack-years) .082 0.588*** 0.724*** 0.869 0.902
Decreases physician's severity estimate

  1. † Betas derived from ordinary least squares regression models, and odds ratios from multiple logistic regression models.
  2. ‡ Compared to reference group of 684 patients with "average disease severity". * = p < .05, ** = p < .01, *** = p < .001
  3. ¶ Scores on this scale range from 0 (worst health or function) to 100 (best health or function)
