Table 2 Hazard ratios, absolute differences for matched and unmatched dataset

From: Thymectomy for non-thymomatous myasthenia gravis: a propensity score matched study

  HR for R/MM status Absolute difference in R/MM at 5 years Probability HR > 1
Standard Cox models
Unmatched data 1.5 (CI: 0.8, 2.8) −3% (CI: −10, 4) --
Matched data 1.9 (CI: 1.6, 2.3)* 15% (CI: 1, 29) --
Bayesian models
Matched data, uninformative prior 2.2 (CrI: 0.9, 6.0) 9% (CrI: −1, 27) 96%
Matched data, skeptical prior 1.2 (CrI: 0.8, 1.6) 2% (CrI: −1, 9) 79%
Unmatched data, uninformative prior 1.9 (CrI: 1.0, 3.3) 20% (CrI: 2, 38) 98%
Unmatched data, skeptical prior 1.2 (CrI: 0.8, 1.7) 4% (CrI: −3, 12) 86%
  1. Values for the standard Cox models are expressed with a 95% confidence interval (CI).
  2. The Bayesian models used 10000 iterations. The values presented are the median and 95% credible intervals (CrI).
  3. HR: Hazard Ratio.
  4. HR > 1 indicates increased likelihood of achieving R/MM, favoring thymectomy.
  5. R/MM: Remission or Minimal Manifestation Status.
  6. *p < 0.0001. p values are not part of Bayesian analyses.
