Erratum to: 'Effects of milk containing only A2 beta casein versus milk containing both A1 and A2 beta casein proteins on gastrointestinal physiology, symptoms of discomfort, and cognitive behavior of people with self-reported intolerance to traditional cows' milk'.

Unfortunately, the original version of this article [1] contained an error. Figure 1 has been updated since it was last uploaded. BCM-7, GSH and MPO have all been removed and PD3 is replaced by VAS. The figure is included here. The figure legend has also been changed. It used to read as:

Fig. 1

Study design. A1 = milk containing A1 and A2 β-casein; A2 = milk containing only A2 β-casein; hs-CRP, highly sensitive C-reactive protein; Hb, hemoglobin; IL-4, interleukin-4; Ig, immunoglobulin; VAS, visual analog scale scores; SCIT, Subtle Cognitive Impairment Test; SCFA, short-chain fatty acids

Study design. A1 = milk containing A1 and A2 β-casein; A2 = milk containing only A2 β-casein; hs-CRP, highly sensitive C-reactive protein; Hb, hemoglobin; IL-4, interleukin-4; Ig, immunoglobulin; BCM-7, β-casomorphin-7; GSH, glutathione; PD3, gastrointestinal symptoms of post-dairy digestive discomfort; SCIT, Subtle Cognitive Impairment Test; SCFA, short-chain fatty acids; MPO, myeloperoxidase.

It has now been changed to read as follows:

There will be an update for these corrections as well as this erratum.
