Using the SAS Output Delivery System (ODS), you can create, customise, and manage HTML output in any operating environment by submitting programming statements. After creating HTML files, you can view them using Internet Explorer, Netscape Navigator, or any Web browser that fully supports HTML 3.2. ODS gives you new formatting options and makes procedure output much more flexible. With ODS, you can easily create HTML, RTF, PCL, PS, XML, Latex and PDF output, an output data set of procedure results and traditional SAS listing output. Also, ODS stores your output in its component parts (data and table definition) so that numerical data retains its full precision. Procedure output is divided into components, or output objects. Depending on the procedure that you run you might have one or several output objects created. For example proc print would create just one output object but proc univariate would produce multiple output objects. ODS stores a link to each output object in the results...

*Creating a flag variable when a test variable meets certain criteria is very common for SAS programmer…. Many SAS programmers use the below code to assign a flag of 1 or 0 depending on of the test variable meets criteria or not.; *Ex:; *Create a test dataset; data test; input id age sex $; cards ; 1 25 Male 2 35 Female 3 29 Female 4 37 Male 5 32 Male ; run ; *Most programmers use the following code to assign avalue of 1 0r 0 to flag variable; data test1; set test; if sex= 'Male' then flag=1; else flag=0; run ; *Some programmers use the following code to do the same task; data test; set test; flag= ifn (sex= 'Male' ,1,0); run ; *You can write ....even simpler code than the above 2 dataset step methods.; data test2; set test; flag= 'Male' =sex; run ; *Or; data test3; set test; flag=sex= 'Male' ; run ; * Note : The above code does the same thing as the 1st and 2nd method; Cave...

Always, programmers need to summarize the demographics data and show it in a table and to do so they use Proc Freq procedure. Even though proc Freq calculates the Frequency exactly, it may not be the write procedure in all cases especially when data do not exist. Some times statistician wants to see all the data values on the CRF in the final table, even though there is no combination as such exists in the dataset. In this case we have to insert observations with 0 values. Here I will present you ….the different methods to insert a zero row. 1) Creating a Dummy Dataset and Concatenate the dummy dataset with the input dataset. 2) Proc Freq SPARSE option 3) Proc Means COMPLETETYPES Option 4) Proc Means COMPLETETYPES O ption with PRELOADFMT option. Dummy Dataset: Adv: Simple and doesn’t need any formats Caveat : Programmer has to know all the possible combinations Sparse Option: Lists all possible combinations of variable levels even when a combination does not occur. Syntax: p...

The Case Report Tabulation (CRT) is the collection of the annotated case report form (CRF), SAS® datasets, metadata, and source programs that comprise a portion of the NDA package submitted to the FDA. The FDA uses it when reviewing submissions. Review starts with the Define document which contains metadata describing the datasets, variables, and values. It is all tied together using internal and external hyperlinks, bookmarks, and destinations to make it easily navigable 1 . The CRT is essentially a collection of data and documentation for a study. It contains features such as bookmarks and links to allow reviewers to easily navigate the submission. For consistency, there are guidelines from FDA1 and CDISC defining the components though the guidelines are limited in scope. We need to create Define Document ( define.pdf or define.xml ) as a part of CRT. Each dataset is a single SAS transport file and, in general, includes a combination of raw and derived data. Each CRF domain (e.g., d...
