The authors have advised there are errors in the text and Table 1 on page 2512 of the published paper.

Table 1 Pearson Correlation Coefficients Between WPAI Subscale Scores and PDQ-D-5 Total Scores

WPAI Subscale	Baseline		Month 1		Month 2		Month 6		rmcorr (n)	p value
	CC (n)	p value	CC (n)	p value	CC (n)	p value	CC (n)	p value
Absenteeism	0.00 (347)	0.94	0.09 (222)	0.18	0.17 (219)	0.01	0.21 (177)	0.004	−0.04 (965)	0.31
Presenteeism	0.50 (290)	< 0.0001	0.63 (161)	< 0.0001	0.61 (168)	< 0.0001	0.56 (155)	< 0.0001	0.51 (774)	< 0.0001
Overall work impairment	0.47 (285)	< 0.0001	0.55 (158)	< 0.0001	0.58 (167)	< 0.0001	0.58 (152)	< 0.0001	0.51 (762)	< 0.0001
Impairment of general activity	0.43 (510)	< 0.0001	0.50 (400)	< 0.0001	0.62 (390)	< 0.0001	0.63 (329)	< 0.0001	0.54 (1629)	< 0.0001

Notes: To integrate all visits in the analyses, rmcorr was used to account for non-independence among repeated measures. A correlation coefficient with an absolute value 0.4–0.7 represents a moderate correlation (blue), while < 0.4 (white) represents a weak correlation. n is the number of observations used for each correlation. P values are statistically significant at the level of 0.001.

Abbreviations: CC, correlations coefficient; rmcorr, repeated measures correlation; PDQ-D-5, Perceived Deficits Questionnaire for Depression–five-item; WPAI, Work Productivity and Activity Impairment.

Validity of the PDQ-D-5 by Comparison with Other Measures section, fourth sentence, the text “PDQ-D-5 scores showed a moderate correlation with the presenteeism (rmcorr, 0.56, p < 0.0001), overall work impairment (rmcorr, 0.58, p < 0.0001), and impairment of general activity (rmcorr, 0.63, p < 0.0001) subscale scores on WPAI, while the correlation with absenteeism scores was weak (rmcorr, 0.21, p < 0.004) (Table 1)” should read “PDQ-D-5 scores showed a moderate correlation with the presenteeism (rmcorr, 0.51, p < 0.0001), overall work impairment (rmcorr, 0.51, p < 0.0001), and impairment of general activity (rmcorr, 0.54, p < 0.0001) subscale scores on WPAI, while the correlation with absenteeism scores was weak (rmcorr, −0.04, p = 0.31) (Table 1)”.

The correct Table 1 is as follows.

The authors confirm that they do not believe that the modifications detailed above affect the interpretation of the results and consider them to be numerical in nature only.

The authors apologize for these errors.
