Nomogram predicting FEV1/FVC ratio. The nomogram is used by first giving each variable a score on the ‘Points’ scale. The scores for all variables are then added to obtain the total score and a vertical line is drawn from the ‘Total Points’ row to estimate the FEV1/FVC ratio. A predicted FEV1/FVC value < 65 or > 90 must be interpreted as ‘less than 65’ or ‘larger than 90’, respectively
