Thus, the CHA 2 DS 2-VASc score is a refinement of CHADS 2 [8] [10] score and extends the latter by including additional common stroke risk factors, that is, age 65–74, female gender and vascular disease. [11] In the CHA 2 DS 2-VASc score, 'age 75 and above' also has extra weight, with 2 points.
Over the years, as he observed many people, he developed the full theory and the method of translating Wechsler scores into PAS profiles. Many refinements in the method used to produce PAS profiles from Wechsler scores were made with the 2001 method and one much older method the most extensively used by psychologists using the PAS.
Psychometric legend has it that a 1–9 scale was used because of the compactness of recording the score as a single digit but Thorndike [1] claims that by reducing scores to just nine values, stanines "reduce the tendency to try to interpret small score differences (p. 131)". The earliest known use of stanines was by the U.S. Army Air Forces ...
The Framingham Risk Score is a sex-specific algorithm used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score was first developed based on data obtained from the Framingham Heart Study, to estimate the 10-year risk of developing coronary heart disease. [1]
The Adjusted Service Rating Score was the system that the United States Army used at the end of World War II in Europe to determine which soldiers were eligible to be repatriated to the United States for discharge from military service as part of Operation Magic Carpet. This system was referred to as "The Point System" by U.S. soldiers.
This same study suggested 7.8 as a general cutoff score when differentiating between healthy older adults and those struggling with chronic stroke symptoms. [ 3 ] In another study of subjects between the ages of 51 and 80, those with scores in the lowest range (0 to 3) were 5–6 times more likely to die within the study period (about 6 years ...
Medical calculators arose because modern medicine makes frequent use of scores and indices that put physicians' memory and calculation skills to the test. [2] The advent of personal computers, the Internet and Web, and more recently personal digital assistants (PDAs) have formed an environment conducive to their development, spread and use.
The two values on the VAS-scales are added up to give a total score ranging from 0 to 100. [8] Higher scores indicate higher levels of fear, and the cut-off point for fear of birth is 60. [ 9 ] Later on, FOBS, was then developed and tested based on Rouhe’s research in pregnant women in both Sweden and Australia.
