Hi, Could someone help with coding this in R? I need to select one row per patient i in clinic j. The data is organized similar to that shown below. Two columns - patient i in column j identify each unique patient. There are two columns on outcome. Some patients have multiple rows with each row representing one visit, coded for in the column, visit. Some patients have just one row indicating

Hello Everyone,   I’m a SAS user who has recently become interested in sequential clinical trials designs. I’ve discovered that the SAS based approaches for these designs are either too costly or are “experimental.” So now I’m looking for alternative software. Two programs that seem promising are SPLUS Seqtrial and R.   I recently obtained a 30 day trial for the SPLUS Seqtrial add-on and have

Dear all, There have been a variety of discussions on the R list regarding the use of R in clinical trials. The following post from the STATA list provides an interesting opinion regarding why SAS remains so popular in this arena: http://www.stata.com/statalist/archive/2008-01/msg00098.html Regards, -Cody Hamilton

Hi, I have a series of id's with multiple visits and questionnaire scores. This is a clinical trial that will be analyzed using the last observation carried forward method. In other words, in order to comply with intent to treat analysis when many subjects withdraw, data points for the last visit must be generated and filled in with the last observation. The ultimate goal is to tabulate the

Hi all, I happened to be reviewing a Linux web site that I frequent (http://www.pclinuxonline.com/index.php) and noted today an entry for an article on R at IBM's developerWorks Server Clinic site located at http://www-106.ibm.com/developerworks/linux/library/l-sc16.html.

Hi, Many thanks to those of you who responded to my last post about Schafer's MI packages. I am really pleased to have access to them through R which, I have to say, is an amazing piece of software. I am only sorry that I haven't found it until now. But, to my question. Does anyone know if there is a package developed for evaluating clinical significance using Jacobson and Truax's,

Does anyone know if for clinical studies the FDA would accept statistical analyses performed with R ? Delphine Fontaine

I am trying to build a model to aid a clinical decision. Certain patients have a blood marker measured at each visit - a rise of this may indicate recurrence of the cancer after treatment (endpoint is "clinical recurrence", censored). In a proportion (up to 30%), this rise is a false positive - hence I wish to correlate factors at the time of the rising test to clinical recurrence,

Is anybody using R to do analysis of clinical trial datasets that have been put in the public domain (which are super hard to find). Not only a single data table, but the actual database, with a handful of data tables with one-to-one or many-to-one relationships? [ For example, "Adverse Events" and "Patient Info" are two datasets with a many-to-one relationship, the

May I ask a clinical question? For a trial, we have a treatment group of small size, say 30 patients. We want to selectmatching control patients from a bigger group (100 patients) in terms of several clinical variables, such as age, tumor stage etc. This practice is to select the closest matching set of control cases. I wonder if R has any routine or package that can help with this problem.
