The 'U'-shaped shape of the age curve for earache is confirmed using multiple regression by a highly significant quadratic effect of age after taking the linear effect into account (p < .001).
The 'U'-shaped shape of the age curve for earache is confirmed using multiple regression by a highly significant quadratic effect of age after taking the linear effect into account (p < .001).
Multiple regression of age at diagnosis, after taking age into account, did find an almost significant difference between the PCD-SI and PCD-SS groups (t 56 = 1.919, p = .060), although the effect was principally due to the outlier, who was aged 63, but diagnosed at the age of five.
Although it might be expected that the age at diagnosis would be lower in individuals who had situs inversus (PCD-SI) than in those with situs solitus (PCD-SS) the trend in this study did not reach statistical significance.
