Abstract:Objective
The purpose of this study were to establish a model of quantitative evaluation that uses the population mean as a baseline of variations and describe variations derived from different types and systems using new concepts.
Methods
The observed datasets, including measurement data and relative data, were transformed to 0–1.0 using the population mean. Datasets derived from different types (same category of dataset, different categories of datasets, and datasets with the same baseline) were transforme… Show more
“…When this ratio is > 1 or <1, this indicates the effect of non-aging factors. To make ratio values > 1 and < 1 comparable, this ratio should be converted based on the research literature [ 25 ]. In light of the combined effects of cumulative and random non-aging factors, the formula for calculating the index of aging (IA) is as follows: where r (the correlation coefficient) is derived from linear regression between age and mortality.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
