KW - IGE N2 - Immunologic data, such as IgE and interleukin 4, tend to have positively skewed distributions with a long tail of larger values. This renders analyses based on normal distribution theory questionable (eg, t tests and analysis of variance)and distorts the sample mean as a measure of central tendency. These problems can be addressed through analysis of log-transformed data. Data analyzed in this fashion are summarized with the geometric mean UR - https://drive.google.com/file/d/1tstYNedxIhFjeT8VCoUxUkv5Ly-GnxO2/view?usp=drivesdk ER -
