In the article that appeared on Page: 825–836, Vol 23 (September 2019) of the Sleep and Breathing [1], one error was discovered in Fig. 4. Because of our carelessness in combining images, we put the wrong images on the CD CIH + SRT group in Fig. 4C, and the figure part of TUNEL-positive cells (%) in Fig. 4 should be denoted by e. The corrected version of Fig. 4 is presented here.

Histological changes induced by SIRT1 activation or inhibition. (A) Representative images of HE-stained hepatic tissues of the four groups (original magnification, × 200). (B) Hepatic fibrosis in the four groups as detected by Masson’s trichrome (original magnification, × 200). (C) Representative images of TUNEL-stained in liver tissues of the four groups (original magnification, × 200). Scale bar = 20 μm. (D) Extent of liver injury in the four groups as graded using the Suzuki score. (E) Percentage of TUNEL-positive cells in the four groups. N = 3, the data are presented as the mean ± SD. *P < 0.05; SRT, SRT1720; sir, sirtinol
