Figure 1 Effect of clinical factors on in-hospital mortality (initial analysis). Only those clinical factors that had a statistically significant impact on mortality are shown. An odds ratio of <1 indicates that the factor is associated with decreased in-hospital mortality. An odds ratio >1 indicates increased in-hospital mortality. bpm = beats per minute; CHF = congestive heart failure; MI = myocardial infarction; SBP = systolic blood pressure.

Figure 2 Effect of clinical factors on in-hospital mortality (patients matched by propensity to have invasive therapy). Only those clinical factors that had a statistically significant impact on mortality are shown. An odds ratio of <1 indicates that the factor is associated with decreased in-hospital mortality. An odds ratio >1 indicates increased in-hospital mortality. Abbreviations as in Figure 1.
