Some observations on the variation in height coefficients in prediction equations for forced vital capacity.
Intercept and height coefficients in prediction equations for forced vital capacity (FVC) are highly correlated and highly variable, due in part to the small coefficient of variation of height (4%). This degree of imprecision and relationship was observed among the coefficients of a set of 26 unrelated published prediction equations, and appeared to dominate any systematic differences between them in methodology and technique.
The findings indicate that care needs to be taken when using equations for predicting the FVC of people at the extremes of height.
