Posterior Means of Parameter Estimates of Model Specified in Equation (i) for Stimulated Saliva Flow Rates and Their 95% Equal Tailed Bayesian Credible Intervals (CI)

Time	Parameter	Posterior Mean	(95% CI)
Baseline	α₀	3.97	(3.87, 4.07)
Dose (1 Month)	α₁₁	−0.025	(−0.034, −0.018)
Dose (3 Months)	α₁₂	−0.019	(−0.026, −0.012)
Dose (6 Months)	α₁₃	−0.0094	(−0.016, −0.0021)
Dose (12 Months)	α₁₄	0.00008	(−0.0072, 0.0074)
Dose (18 Months)	α₁₅	0.0096	(0.0022, 0.017)
Dose (24 Months)	α₁₆	0.014	(0.0063, 0.022)
^†(Dose - 25)⁺	α₂	−0.12	(−0.15, −0.099)
^† (Dose - 45)⁺	α₃	0.070	(0.018, 0.12)

^†

(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.
