Table 2. Change in perfusion of single zones from baseline to eight weeks after EBV treatment.
| Baseline | Week 8 | Absolute change in perfusion (95% CI) | Relative change in perfusion | p-value | |
|---|---|---|---|---|---|
| Target zone | 8.91 ± 3.77 | 5.06 ± 2.76 | −3.86 (−5.10–−2.61) | −43.32% | <0.001 |
| Ipsilateral, nontargeted zone | 36.39 ± 7.98 | 36.99 ± 9.58 | +0.61 (−1.40–+2.61) | +1.68% | 0.54 |
| Total ipsilateral lung | 45.29 ± 9.44 | 42.82 ± 10.99 | −2.47 (−5.06–+0.11) | −5.45% | 0.06 |
| Contralateral, concordant zone | 14.23 ± 5.57 | 15.10 ± 6.55 | +0.87 (−1.01–+2.74) | +6.11% | 0.35 |
| Contralateral, non-concordant zone | 40.09 ± 7.46 | 42.81 ± 8.59 | +2.72 (+1.11–+4.34) | +6.78% | <0.01 |
| Total contralateral lung | 54.70 ± 9.44 | 57.95 ± 10.42 | +3.26 (+1.11–+5.41) | +5.96% | <0.01 |
Data are presented as mean percentage (±SD) of whole lung perfusion, absolute intrazonal percentage change and 95% Confidence Interval (in parentheses) or relative intrazonal percentage change from baseline value.
