Hi All, Just a quick query, I wondered what predicted values for spirometry to use for an employee undergoing gender realignment? I am thinking that the values for the original gender should be used to predict expected values but that doesn't seem very respectful. Any ideas? ******************************** Please remove this footer before replying.
