16. Weaknesses So much missing data Children ‘dropped out’ and ‘dropped in’ Performance testing limited on simultaneous group due to young age Performance testing skewed by results only being obtained if child could do the test 3 year interval only introduced in final year, so limited data Longitudinal study in children – children get older each year!

17. Strengths This is the population not a sample! Unique and real picture of what children with bilateral CI can do Cases not biased Great example of collaborative work throughout UK
