Relationship between IOP and FEV1/FVC. Study participants are stratified to show how IOP changes with decreasing FEV1/FVC in the Jikei dataset (A), using the group with FEV1/FVC above 90% as a reference, and in the JNDS dataset (B), using the group with FEV1/FVC above 95% as reference. A positive linear correlation is observed between FEV1/FVC and IOP. IOP, intraocular pressure; FEV1, forced expiratory volume in one second; FVC, forced vital capacity; JNDS, Japan Ningen Dock Study.
