A study was done about non-participation during Phase III of the International Study of Asthma and Allergy in Childhood (ISAAC III) in Valencia to determine whether the non-response rate significantly affected the results obtained in Valencia. Of the schools selected to participate in ISAAC III, 13.3% denied not to, the main reason being they were already participated in a similar study. The ISAAC III questionnaire was handed out to participating schools for the parents of 6,358 schoolchildren aged 6-7 years. Of these, 53.4% responded correctly. The remaining 46.6% were given a non-response questionnaire (NRQ), of which 4.1% completed the questionnaire correctly. The main reason why parents who received the NRQ did not participate in ISAAC III was that their children had neither asthma nor other atopic disease, so interest was null. No significant statistical differences were observed between the prevalence of asthma in the schoolchildren who participated in ISAAC III and in the non-participants who answered the NRQ. These results suggest that the ISAAC III results relating to asthma are not biased by non-response.
在巴伦西亚进行了一项关于儿童哮喘和过敏国际研究（ISAAC III）第三阶段未参与情况的研究，以确定无应答率是否会显著影响在巴伦西亚获得的结果。在被选中参与ISAAC III的学校中，13.3%拒绝参与，主要原因是他们已经参与了一项类似的研究。ISAAC III问卷被分发给参与学校中6358名6 - 7岁学童的家长。其中，53.4%正确作答。其余46.6%收到了无应答问卷（NRQ），其中4.1%正确完成了问卷。收到NRQ的家长未参与ISAAC III的主要原因是他们的孩子既没有哮喘也没有其他特应性疾病，所以兴趣为零。在参与ISAAC III的学童和回答了NRQ的未参与者中，哮喘患病率未观察到显著的统计学差异。这些结果表明，与哮喘相关的ISAAC III结果不会因无应答而产生偏差。
