Table 4.
Prevalence of dysphagia, based on the Functional Oral Intake Scale, in children with repaired OA in age groups <1, 1–4, 5–11 and 12–18 years
| Age group | <1 year | 1–4 years | 5–11 years | 12–18 years | ||||
|---|---|---|---|---|---|---|---|---|
| Number of OA patients | 111 | 106 | 64 | 24 | ||||
| % (n) | 95 % CI | % (n) | 95 % CI | % (n) | 95 % CI | % (n) | 95 % CI | |
| Dysphagia | 55 (61) | 45–64 | 51 (54)a | 41–61 | 17 (11)b | 9–29 | 21 (5)c | 7–42 |
| Percentage oropharyngeal dysphagiad | 37 (22) | 25–50 | 21 (11) | 11–34 | 27 (3) | 6–60 | 20 (1) | 1–71 |
| Percentage oesophageal dysphagiad | 63 (38) | 50–75 | 79 (42) | 66–89 | 73 (8) | 39–94 | 80 (4) | 28–99 |
a–c p value was calculated to for change in percentage of dysphagia in a age group 1–4 compared to age group <1 year (p = 0,5126), bage group 5–11 compared to age group 1–4 years (p = < 0,001), cage group 12–18 compared to age group 5–11 (p = 0,8575). dData on sensation of food impaction and oesophageal dilatation in one patient with dysphagia were missing in age groups <1 and 1–4 years due to treatment in a foreign country until the age of 5 years
OA oesophageal atresia, 95 % CI 95 % confidence interval for percentage was calculated
