When this article was first published online, the below listed tabulated data were incorrectly mentioned in the article.
In Table 2, the p-value for the intergroup difference of vitamin E intake was listed as < 0.001. This has been corrected as p = 0.177. The error in p-value for vitamin E was not carried over into the main text and hence the interpretations on vitamin E remain correct as published.
Table 3:
(a) The vitamin B12 supplement intake frequency in the vegan group was given as 89.47% (n = 34/38 participants), which has been corrected as 92.11% (n = 35/38 participants). Correspondingly, the number of vegans not supplementing vitamin B12 is n = 3 (7.89%). The overall p-value remains unaltered as p < 0.001.
(b) The general supplement intake frequency in the vegan group was reported as 86.84% (n = 33/38 participants), which has been corrected as 94.74% (n = 36/38 participants). Correspondingly, the number of vegans not taking supplements is n = 2 (5.26%). The overall p-value remains insignificant (0.090). These frequencies were mentioned in the text, as follows:
Abstract: “Fewer lacto-ovo-vegetarians used B12 supplements compared to vegans (51% versus 90%)”. This should have read: 51% versus 92%.
Results: Page 6, “Supplementation behavior”: “A total of 77.5–86.8% of participants took supplements in each group”. This should have read: 77.5–94.74%.
Results: Page 6, “Supplementation behavior”: “The number of participants supplementing vitamin B12 was highest in vegans (89.5%), as well.” This should have read: (92%). This frequency counting error affected only the above-mentioned proportions. Intake frequencies and dosages remain correct as published.
(c) We reported a median docosahexaenoic acid supplement intake in the lacto-ovo-vegetarian group of 185 (330) mg. However, the correct dosage is 441 (469) mg. The p-value remains unaffected.
Table 4:
(a) The standard deviation for red blood cell count in the lacto-ovo-vegetarian group was listed as 4.5 ± 0.05. This has been corrected as 4.55 ± 0.48.
(b) The p-value for parathyroid hormone in serum was listed as p = 0.093. This has been corrected as p = 0.83. The interpretation remains correct as published.
