Contribution of Each Processing Method to Bleed Detection
| Processing method | n | Mean contribution (%) | 95% CI of mean (%) | P against conventional | P against reference subtraction | P against alternate sequential subtraction |
|---|---|---|---|---|---|---|
| Conventional | 116 | 84.8 | 81.3–88.3 | <0.001 | <0.001 | |
| Reference subtraction | 116 | 3.6 | 2.1–5.1 | <0.001 | <0.001 | |
| Alternate sequential subtraction | 116 | 11.6 | 8.5–14.7 | <0.001 | <0.001 |
Statistically significant differences between means are supported by lack of overlap of 95% CIs.
