The absolute values on the predicted look pretty low and I would start by checking those: did they enter the right age? Does she have kyphoskoliosis and we need to use her arm span instead of height? Then there is ethnicity, which will affect the predicted values though I doubt they would change that much. Finally has she had a sex-change operation? If she was born a man we should use male predicted values for her spiro.
The reference says 0.92 liters. That's because she is 93 years old. Just a nic example of how one should interpret percent-predicte vlues with extremes of age...
