Although the ALSFRS-R score is a recognized prognostic indicator, [5] it is more useful to compare various indicators including vital capacity (FVC%) and the Sickness Impact Profile (SIP) [5] [12] to increase the accuracy of a given prognosis. Relating the ALSFRS-R score to staging criteria is also useful in determining prognosis.
The ALSFRS-R is the most frequently used outcome measure in clinical trials [39] and is used by doctors to track disease progression. [40] Though the degree of variability is high and a small percentage of people have a much slower progression, on average people with ALS lose about 1 ALSFRS-R point per month. [41]
In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. [16] [17] [18] The NEWS score is the largest national EWS effort to date and has been adopted by some international healthcare services. [1] A second version of the score was introduced in 2017.
Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
PatientsLikeMe launched its first online community for ALS patients in 2006. [7] From there, the company began adding other communities for other life-changing conditions, including multiple sclerosis (MS), Parkinson's disease, fibromyalgia, HIV, chronic fatigue syndrome, mood disorders, epilepsy, [8] organ transplantation, progressive supranuclear palsy, multiple system atrophy, and Devic's ...
Most R scores fall between 15 and 35, but any real number is a possible R score since the z-scores tend to positive or negative infinity as the standard deviation decreases. To guarantee that a grade of 100 produces an R score of at least 35, an adjusted Z score formula guaranteed to produce a result above 35 is used.
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.
In medicine (oncology and other fields), performance status is an attempt to quantify cancer patients' general well-being and activities of daily life. This measure is used to determine whether they can receive chemotherapy, whether dose adjustment is necessary, and as a measure for the required intensity of palliative care.
