PSQI, Pittsburgh Sleep Quality Index; SD, standard deviation; ASA, acetylsalicylic acid intolerance. Allergy by patient history was self-reported. Allergy by testing was indicated if subjects underwent skin prick or mRAST testing. P-values are reported for differences in PSQI total score for each patient characteristic.
