| Educational provision — no./total no. (%) | |||||
| Mainstream school | 301 | 88/148 (59) | 85/153 (56) | 0.90 (0.54 to 1.49) | 0.69 |

Plus–minus values are means ±SD. Data for scores in areas of study and for special-education needs were obtained from teacher questionnaires (for 225 of 319 children), and data on mainstream school were obtained from parent questionnaires (for 305 of 319 children).
School-attainment scores were missing or not applicable for the following subjects: English or literacy for 2 children in the conventional-ventilation group and 4 in the HFOV group, mathematics for 4 and 3, respectively, art and design for 9 and 8, respectively, geography for 10 and 9, respectively, history for 11 and 9, respectively, information technology for 12 and 9, respectively, science for 6 and 4, respectively, design and technology for 17 and 11, respectively, and the average of all subjects for 1 and 3, respectively. Mainstream-school data were missing for 2 children in the conventionaltherapy group and 2 in the HFOV group. Special education data were missing for 1 child in the conventional-therapy group.
Teachers of children in mainstream schools rated each child’s performance in eight school subjects, according to the following scores: 1 indicated very below average, 2 below average, 3 average, 4 above average, and 5 very above average. The average subject score is the mean of all available subject scores.
Results were based on the teacher’s yes-or-no response to the question, “Does this child have any special-education needs?”
