Table 2 Criteria used to classify intervention effectiveness, with examples of outcomes reflecting each level of effectiveness
Outcome Score | Criteria | Example |
|---|---|---|
0 | • No statistically differences between control and intervention groups, or between intervention and baseline, on process or outcome measures | • No difference in adherence, NYHA class, # visits, or # hospitalizations |
0.5 | • Trends without significance • Mixed outcomes (significant improvement in minority of measures) • Significant improvement compared with baseline, but not with control | • Significant improvement in adherence, trends for CHF-related admission and total number of hospital days |
1 | • Statistically significant improvement: -all outcomes if ≤3 endpoints -majority of outcomes if > 3 endpoints | • Significant reduction in all-cause mortality and all-cause admissions at 3 months |
