Changes of ALT (IU/L) over time assessed by linear mixed effects models for patients treated with TDF vs. untreated

	Crude model		Adjusted for baseline age, gender, ethnicity
	Coefficient β (95% CI)	p-value	Coefficient β (95% CI)	p-value
(Intercept)	30.182 (26.944, 33.421)	< 0.001	44.491 (35.438, 53.545)	< 0.001
Group	23.566 (17.691, 29.440)	< 0.001	21.868 (16.058, 27.677)	< 0.001
Time	−0.055 (− 0.169, 0.059)	0.346	− 0.055 (− 0.168, 0.059)	0.347
