To grade severity of mixed restrictive/obstructive disease, just divide FEV1% by TLC%, authors propose

ATS / ERS guidelines recommend using % predicted FEV1 as the metric to define severity of obstructive, restrictive, and mixed ventilatory disorders. The main driver: FEV1 is the most robust variable as an overall measure of health (epidemiologically speaking). Critics charge that this overestimates severity of obstruction when restriction is also present, causing confusion, misdiagnosis, and over-treatment. Back in 2002,
