t Test (for paired data) for a difference in mean bone conduction hearing loss (better ear) in COPD cases and controls

COPD cases and controls tested by PTA Mean bone conduction hearing loss (better ear) in dB
COPD cases N=97 27.9 (SD 14.2)*
Controls N=97 23.7 (SD 13.5)

*Significant difference p=0.006.

COPD, chronic obstructive pulmonary disease; PTA, pure tone audiometry.
