Characteristics of the Fractional Amplitude of Low-Frequency Fluctuation in Ocular
In the original article, there was a mistake in Table 2. Demographics and behavioral results of OH and HCs groups as published. The age of HC was incorrectly listed as 50.36 ± 54.22. The correct age of HC is 50.36 ± 5.42. The corrected Table 2 appears below.
In the original article, there was an error in the section Materials and Methods, sub-section Subjects. The subject characteristics: "18 HC patients (8 males and 8 females; mean age 50.36 ± 54.22 years; age range 20-60 years)" is incorrect. The correct sentence is: "18 HCs (9 males and 9 females; mean age 50.36 ± 5.42 years; age range 20-60 years)".
In the original article, there was an error in the section Results, sub-section The Use of ROC. The sentence: "To test whether the ROC curve has potential as a diagnostic marker for OH, ROC curves were constructed using mean fALFF values of the two brain regions in the OH and HC groups. An area under the curve of 0.5-0.7 is considered to indicate low accuracy, 0.7-0.9 higher accuracy, and an area higher than 0.9 represents good accuracy. Accuracy was low in the left anterior cingulate gyrus (LAC) (0.9892; P < 0.0001; Figure 4A) and higher in the left anterior cuneiform (LP) > HC (0.8834; P < 0.0001; Figure 4B)." is incorrect. The sentence should be: "To test whether the fALFF value has potential as a diagnostic marker for OH, ROC curves were constructed using mean fALFF values of the two brain regions in the OH and HC groups. An area under the curve of 0.5-0.7 is considered to indicate low accuracy, 0.7-0.9 higher accuracy, and an area higher than 0.9 represents good accuracy. Accuracy was high in the left anterior cingulate gyrus (LAC) (0.9892; P < 0.0001; Figure 4A) and lower in the left precuneus (LP) (0.8834; P < 0.0001; Figure 4B)." In the original article, there was an error in section Results, sub-section The fALFF Value. The values in the sentence: "The fALFF value of LP in the OH group was higher than in the HC group (t = 5.5535), while the fALFF value of LAC in the OH group was decreased (t = −3.7520; Figure 5)" are incorrect. They should be: "The fALFF value of LP in the OH group was higher than in the HC group (t = −3.7520); while the fALFF value of LAC in the OH group was decreased (t = 5.5535) (Figure 5)." The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
