In order to compare current and former smokers in terms of continuous variables (such as age of onset of smoking, length of smoking, number of cigarettes/day smoked at the onset of CH, and number of cigarettes/day smoked at the time of completing the questionnaire), means ± SD were calculated between groups and the Student's t-test was carried out.
The onset of GHD GHDD length) was identified on the basis of clinical history (first diagnosis of pituitary disease, prior surgery, and, if any, previous chemical assays).
Confounding variables – the list included age of onset, length of illness, total number of episodes, polarity of the intake episode, family history of psychiatric disorders, psychotic features, comorbid personality disorders and treatment history – asymmetrically distributed between PPO and NPPO samples (p < 0.05) were controlled for using ANCOVA.
Survival to hypoxia exposure varied with developmental time of onset, length of exposure time, and severity of hypoxia.
Hearing ability in cochlear implant recipients varies from almost normal to only perceiving environmental sounds and depends on such factors as the individual's hearing history, age of onset and length of deafness, and age of implantation.

An increasing body of evidence shows that spine deformity can be successfully controlled until the onset of puberty; spinal length increases and the inexorable pulmonary decline can be halted, and even improved, in most children.
Since telomeres shorten with age and oxidative stress, both of which are important contributors to the onset of dementia, telomere length might be a valuable biomarker.
Six weeks prior to the onset of experimentation, fork length (cm) and mass (g) measurements were recorded for all anadromous males and females.
