Hello sir, Appreciate your effort and teaching skills,. Your website is completely different compared to your videos on RU-vid. there is no input data and output dataset and also many tabs are missing, it would be helpful if we could see the input and output of your programs in your blog.
for various reasons, we cannot provide some of the files used in videos cannot be shared... the main purpose of the videos is to help viewers understand the concept... you can reach us using contact us page on the website if you need more details
it's not a repeat... the first instance is creaing the temporary variable named _x using indsname option of the set statement. second instance is creating a permanent variable named indsname by using the value from _x.
?? is an informat modifier which tells sas to convert the values to numeric only if its a valid numeric value and do not write any message to log file for invalid numeric data...
glad you found it helpful... the flow of an efficacy will remain the as other adam datasets as the underlying principles are same for safety and efficacy datasets...
Hi sir, Good Evening, excellent explanation. Could you please video on WOCF and BLOCF derivation and also kindly request please do video on rescreening subjects, Thank you.
it's just a placeholder filter... it technically filters all data from the input dataset... output wouldn't be impacted even if we remove that line of code
Hi sir as per spec we assign dsstdtc variable derivation, but my doubt is most of the cases we must and should assign rficdtc variable direct from DM domain to rficdt variable correct sir??
Hi @mycsg thanks for the easy understanding way of teaching. I have a little confusion about Domains like in my mnc most of them communicate as EFFICACY Domains, SAFETY Domains. What are they and on what basis they were classified as it is.
a dataset may get classified as efficacy if it contains some information that is used to evaluate efficacy as determined in the protocol... all the other datasets may get classified as safety... so, the classification of the data using this terminology is very study specific...
if pk samples are collected after different doses, the value in pcrftdtc will differ on different rows . so, we cannot directly assume that it is same as rfstdtc without knowing the study design
Cannot stress how valuable this channel is going to be. I found this a day prior to my interview for the Clinical DBA role at an oncology center and I have binged through your videos all afternoon. Unlike other channels, you have amazing explanation and presentation skills, your mic is good, wwell defined and segregated playlists and a webstie with loads of resources to learn from. I would definitely carry on learning from you. If I happen to secure this job, my success at work will be owed to you
Hi Joel, your comment actually resonates with the vision and purpose of existence of the channel and website... glad you found it helpful... all the best...
Sir pls answer ..Is it compulsory to done SAS training from SAS website of US for getting certificate? Or 2nd method is that we can learn from you and give only test for certification.. what's your view about this pls share..
it's not mandatory to learn sas directly from sas institute... you can learn sas anywhere and get certification done... btw, we don't provide any training as of now...
Any recommendations on additional studying for the sas base programming cert with limited budget? I appreciate these videos, they are very helpful for my review.
It may take some time. Now that you are aware of how to look at the medical concepts and associated SDTM domains, you should try to visualize/remember things based on the description of the domain.
big N is the total participants who received a particular treatment. small 'n' is the number of participants who had a particular adverse event.. Not all participants may experience a particular event, so 'n' will be less than or equals to 'N'..
Hi Sir Good morning, Great information, I have a doubt what is difference between sdtmigv3.2 and sdtmig3.3. And I kindly request please do video for re-screening subjects.
Hi, the best place understand the modifications between ig 3.2 and ig3.3 is to refer the section 1.3 of ig 3.3. I will try to create a video on re-screening subjects soon.
1) Analysis flags can be added in OCCDS datasets. 2) These two variables differ by definition and purpose. Criteria flags are used to identify if a record meets a 'predefined criteria' like systolic blood pressure > 160 etc. Most often these are based on AVAL, CHG, PCHG, R2BASE etc. On treatment flag is a standard variable which is used to identify if a record can be attributed to the treatment based on comparison of treatment start and end dates.
@@mycsg thanks for explaining them so clearly. I have a request could you make videos on interview questions w.r.t to ADaM TLFS for experienced candidates
What is the best way to make it work the next day? It only works on the same workday but I can't open the file the next day even though it is still pinned.
is this happening in a remote desktop like citrix connection? in such systems, sometimes, user profiles are reset on each sigin in and these kind of setting get lost..
with some vaccines, symptoms like fever and body pains are expected, such expected symptoms are considered as soloicited... similarly for injection based vaccines , pain, redness at the site of injection are expected.. those are also considered solicited... all other events which are not considered solicited in the protocol are considered unsolicited...
Sir, Thank you for all these videos they are comprehensive and very useful. Could you please let me know about Trial disease assessment which comes under Trial design domain itself
