We explored models with two to seven classes using all measures, and systematically eliminated variables and levels of variables that did not distinguish between classes, tested categorical variables derived from count measures, and combined variables that were highly collinear.
Few monitoring systems exist in the Eastern Mediterranean and Middle East to systematically measure variables such as temperature, humidity and desertification.
The objectives of this study are to describe the processes of care and determine risk factors predictive of poor outcomes for TBI patients presenting to Mulago National Referral Hospital (MNRH), Kampala, Uganda.We used a prospective neurosurgical registry based on Research Electronic Data Capture (REDCap) to systematically collect variables spanning 8 categories.
We systematically examined variables affecting the power to detect anti-epileptic effects by ECoG and used a non-parametric bootstrap strategy to test several different statistics, study designs, statistical tests, and impact of non-responders.
In the present study, we examined the performance of common marmosets (Callithrix jacchus) on support problems to address questions about their understanding of such problems by systematically manipulating variables that might affect their performance.
Of the three codon positions, third position nucleotides were systematically more variable than those of first and second positions as measured by percentage of sites that were variable and the percentages of sites that were parsimony informative (data not shown).
We synthesized "instrumental chimeras" that systematically combined variable amounts of envelope and fine structure in 25\% increments from two different source instruments with either sustained or percussive envelopes.
In particular, by systematically examining variable pitch naming ability we have identified component neurocognitive processes that are differentially involved in the representation of pitch.
However, these studies have been small (n=197, 761, 68, 679, 210, 54 and 166 respectively) and in many cases have not been able to systematically examine variable cortisol level cut-offs or determine the impact of underlying aetiology and specifically the clinical problem of iatrogenic adrenal insufficiency.
