Baseline	α₀	2.44	(2.261, 2.40)
Dose (1 Month)	α₁₁	−0.0447	(−0.0625, −0.0491)
Dose (3 Months)	α₁₂	−0.0499	(−0.0688, −0.0544)
Dose (6 Months)	α₁₃	−0.0499	(−0.0701, −0.0544)
Dose (12 Months)	α₁₄	−0.0262	(−0.0415, −0.0302)
Dose (18 Months)	α₁₅	−0.0229	(−0.0396, −0.0272)
Dose (24 Months)	α₁₆	−0.00633	(−0.0226, −0.0107)
^† (Dose - 25)⁺	α₂	−0.0609	(−0.108, −0.0741)

^†

(Dose - 25)⁺ represents the difference between radiation dose and 25 if the dose is greater than 25Gy, otherwise, the quantity equals 0. (Dose - 45)⁺ is similarly defined.
