Dosimetric parameters for asymptomatic and symptomatic cases.

Parameter	Asymptomatic (4 cases)	Symptomatic (26 cases)	P-value

MLD	7.0 (3.0 - 14.7)	8.4 (4.4 - 12.0)	0.69
V₅	37.9 (11.9 - 63.8)	39.2 (18.5 - 56.1)	0.93
V₁₀	24.2 (8.5 - 43.8)	28.8 (15.9 - 39.9)	0.93
V₂₀	13.2 (4.6 - 26.3)	16.8 (11.8 - 24.5)	0.56
V₃₀	7.3 (1.3 - 18.8)	6.2 (2.3 - 12.2)	0.78

Median value with range given in parentheses for each entry. P-values calculated using the Wilcoxon rank sum test. P-values of 0.05 or less were considered statistically significant.

Abbreviations: MLD = mean lung dose; V₅ = percentage of lung receiving ≥5 Gy; V₁₀ = percentage of lung receiving ≥10 Gy; V₂₀ = percentage of lung receiving ≥20 Gy; V₃₀ = percentage of lung receiving ≥30 Gy.
