Benfer KA, Weir KA, Bell KL, et al. Longitudinal cohort protocol study of oropharyngeal dysphagia: relationships to gross motor attainment, growth and nutritional status in preschool children with cerebral palsy. BMJ Open 2012;2:e001460. A number of author corrections were inadvertently missed during the proofing stage:

1. The title of this paper should read: ‘Protocol for a longitudinal cohort study of oropharyngeal dysphagia: relationships to gross motor attainment, growth and nutritional status in preschool children with cerebral palsy.’

2. Under the section “Aims and hypotheses” the expansion of DDS is actually “Dysphagia Disorders Survey” (not “Schedule”).

3. Under the section “Thomas-Stonell & Greenburg Scale—saliva control”, paragraph 2, reference 53 should be after “Scale” (as this is part of the measure name).

4. Table 2: H2(A) –These are all the same hypothesis, so all instances should have been in upper case A.
