Examination length was restricted to reduce the duration of the anaesthesia therefore not all measurements were taken on all conceptuus.
Demographic and medical variables were retrieved from institutional medical records: age, gender, last psychiatric diagnosis (according to the International Classification of Diseases 10th Revision: ICD-10), prescribed drugs at the time of examination, length of hospitalization (time spent in the psychiatric institution).
The relationship between examination length and reliability is formalised in the Spearman-Brown formula: The Spearman-Brown formula shows not only that in order to increase the reliability of an examination it has to be made much longer, but it also shows by how much longer.
Controlling for the endogeneity of outsourcing decision as well as the changes in the time resources available for an examiner, we find that the outsourcing of prior art search significantly decreases the frequency of appeals against both examiners' rejections and grant decisions and reduces the length of examination duration.
Lifestyle factors were: maternal/paternal smoking status (from parental questionnaire responses) and BMI (from parental examination); leg length (from MFS participants' physical examination, categorised as < vs. ≥ the sex-specific median value).
The physical examination included length, weight, BMI, and standardised blood pressure measurement.
For routine histological examination, the length of duodenal villi was assessed using an ocular micrometer.
In the acute phase compared to control examination, the length of the vitreous cavity was shallower in the patients with CNS findings (mean difference 0.5 mm, p < 0.01) than in the other patients with acute NE (mean difference 0.2 mm).
The following variables were assessed before and after dilation: diurnal IOP, anterior segment examination, axial length (AL), anterior chamber depth (ACD), central corneal thickness (CCT), anterior chamber flare with laser flare photometer (FM-500, Kowa, Tokyo, Japan), and anterior chamber angle with Visante OCT (Carl Zeiss Meditec, Dubin, CA, USA).
However admirable a high reliability may be, it seems unlikely that candidates or examiners would tolerate an examination of that length (particularly as it would be proportionately more expensive and time-consuming to set).
Although pre-1850 voccasionallyionally docked at the Cape of Good Hope, an examination of the length of six voyages in the 1830s (not reported in this study), between England, South Africa and Australia indicated that the length of each individual leg makes it unlikely that measles outbreaks would have lasted long enough on the second part of the journey to reach Australia.
