mssstest - Normalisationo of disease scores - originally developed for the EDSS for Multiple Sclerosis
mssstest
Suppose one is interested in determining whether the genotype at
some locus of interest affects the rate of progression of disease of people
with Multiple Sclerosis (MS). One method would be to calculate the mean EDSS
score in patients with each of the genotypes and test whether they are
significantly different. However, this approach is inefficient if patients
have their EDSS assessed at different durations of disease, as patients who
have had MS longer typically have higher EDSS scores regardless of their
genotype. By adjusting for duration, a more powerful test can be developed.
MSSStest is a program for implementing the method described in the article The
Multiple Sclerosis Severity Score. R. Roxburgh S. Seaman et al. (2004),
accepted for publication by Neurology. It calculates MSSS scores and uses
these scores to test for differences between disease progression rates in
different groups defined by genotype at some locus.
To use the program first copy the table of disease scores to the current
directory. You are expected to use the EDSS scores provided by the
authors.
The program does not accept options, it should, though. The output goes to the files "msss.out" and "indivmsss.out".
