A substantial portion of effectiveness studies reviewed concluded that preterm infant prophylaxis, especially in those with associated risk factors, was cost-effective in terms of the cost per Quality Adjusted Life Years (QALY) gained [ 57– 62] 62].
PCA was originally described by Dr. Frank Benson and colleagues in 1988 (Benson DF, et al., Arch Neurol 1988; 45:789-793), and is sometimes referred to as Benson's syndrome or the visual variant of Alzheimer's disease because a substantial portion of patients studied so far harbor underlying Alzheimer pathology in the brain, although there are other causes as well.
The topography of Nigeria and indeed the study area is a reflection of its geology, as the Basement Complex rocks of the SW-Nigeria are responsible for the rugged topography that dominates substantial portion of the study area.
Therefore, a substantial portion of recently published studies has design flaws that limit reproducibility and comparisons with other and/or future studies.
Because the USGCRP considers both climate change and stratospheric ozone depletion to be aspects of global change, NIH has traditionally included a substantial portion of its UV effects studies in its climate change portfolio, which is reported to the USGCRP.
In particular, six categories of ways of understanding emerged from the data as having been shared by a substantial portion of the students in this study: (1) covariation, (2) invoking time, (3) other symbols as constants, (4) other symbols as implicit functions, (5) implicit differentiation, and (6) output values as amounts instead of rates of change.
Several observational as well as biochemical studies have led to a prevalent hypothesis that nutritional status may account for a substantial portion of this variability, though no controlled clinical studies have addressed this important hypothesis.
In the large cohort of the EuroBCM in PD study, a substantial portion of patients were fluid overloaded by more than 1.1 litre, the 90th percentile of absolute Δtissue hydration in the normal reference population [29], and 25% of patients had a relativeΔ tissue hydration/extracellular water ratio above 15%, a value associated with increased mortality in HD patients [20].
In our study, a substantial portion of the perpetrators committed suicide at the crime scene (Finland 30%, Austria 18%).
UniGene IDs have been used as the matching criterion to merge data across various platforms, but this has led to a substantial portion of the data remaining unmatched in previous studies [4], [5], [6], [7], [8].
