I was requested by a friend's mother to analyze her data from her past treatment. Since she got leukemia two years ago, she had been instutionlized for various periods and underwent various treatments. So I can download a data chart with time points and measurement after medicine A, B,C,D, E, etc. However the measurements were not on a level enable me to comparing them with one another via a simple graph, but more like heart rate and blood pressure which must be somewhat related, however having a different mean and standard deviation. With 5-6 medicine at hand and 2 years data available to me, I could not really analyze the data properly as I am a mathematican without proper training in statistics. But now I want to ask about this in general, because the friend had died from the leukemia, and I wish I could have been making some difference, despite the fact that there is absolutely no cure for her type.
The question I want to ask out of this personal experience is: to what extent can we help (real) patients via statistical methods? How can we manage to extract the hidden relation behind a not so large discrete set of data (300-600 data points, say) and have reasonable confidence this might mean something? Suppose we had all the programming power available and money issue is not really a concern, is there any real hope we can garner personal data to help a patient on an indivudal level? I was not a statistican, and I tried linear regression between the variables, which failed miserably as there seemed to be no obvious relationship between them. So I want to ask a professional's viewpoint on this.
(I had read at least 100+ leukemia papers to try find something that might help either biologically or via mathematical biology like population dynamics, but I failed)
I forgot to write that metamed (a medical start-up company) does offer individual tailored medical analysis, seems mostly based on patients' genetic data. They charge an extremely high price. However I do not know if their service is reliable. In my personal case, my friends' family decided against seeking their help. I do not really know if this would make any difference, for in her case all the therapeutic (experimental or well-established) methods has been exhausted. Since this thread may be of interest to others, I decided to include this 25c at here.
