Longitudinal Associations of PTA, WRCM, TMT Over 10-Year Follow-up

% Change in WRCM (95% CI)		SD Change in TMT (95% CI)		SD Change in TMT (95% CI)
[Standardized effect]a		[Standardized effect]a,b		[Standardized effect]a,c
Determinant		Determinant		Determinant
Age, yr	–0.37 (–0.47, –0.27) [ß = –.21]	Age, yr	0.03 (0.02, 0.04) [ß = .27]	Age, yr	0.007 (0.001, 0.01) [ß = .06]
PTA, dB	–0.36 (–0.42, –0.29) [ß = –.22]	WRCM, %	–0.002 (–0.003, 0.0003) [ß = –.02]	PTA, dB	0.005 (0.001, 0.01) [ß = .05]
PTA × age, dB/yr	–0.03 (–0.03, –0.02) [ß = –.28]	WRCM × age, %/yr	–0.0003 (–0.0004, –0.0001) [ß = –.14]	PTA × age, dB/yr	0.001 (0.0002, 0.001) [ß = .09]

Note: DB = decibel; PTA = pure-tone average 0.5–4 kHz; SD = standard deviation; TMT = trail-making test; WRCM = word recognition in competing message.
