Contribution of Each Processing Method to Interpretive Confidence
| Processing method | n | Mean contribution (%) | 95% CI of mean (%) | P against conventional | P against reference subtraction | P against alternate sequential subtraction |
|---|---|---|---|---|---|---|
| Conventional | 158 | 83.8 | 81.0–86.6 | <0.001 | <0.001 | |
| Reference subtraction | 158 | 5.0 | 3.7–6.4 | <0.001 | <0.001 | |
| Alternate sequential subtraction | 158 | 11.2 | 8.7–13.7 | <0.001 | <0.001 |
Statistically significant differences between means are supported by lack of overlap of 95% CIs.
