Table 1. Odds ratios with 95% confidence intervals (in square brackets) of treatment comparisons in the original smoking cessation data and those after event status modifications for deriving the fragility index for each comparison.

Results in italic indicate the target treatment comparison for which the fragility index is derived. Treatment indexes: 1) no contact; 2) self-help; 3) individual counseling; and 4) group counseling.
