Warning related to the concepts_to_exclude list and the PS file #209

Hi

I have a PLE study where the basic aim is to compare the groups with blood glucose level above and below 7.7.

I get the following warning when I run the PLE script:

It also gives the same propensity score value to all the records in the PS file.

Based on the warning, I have checked the concepts_to_exclude list (which includes the concepts related to the blood glucose level), and have tried changing/adding/removing the concepts in that list, but it still didn’t resolve the warning and the problem with the propensity scores. Additionally, I have also tried adding and removing several covariates from the createDefaultCovaraiteSettings(), but it didn’t help too.

Do you have any idea about how to resolve this issue?

I have also attached the sessionInfo of the R session for your consideration. Pls let me know if you need any other information.

@malihamashkoor123 - sorry for the very long delay here. It is hard to troubleshoot this without the full script for the study as we'd need to understand the target/comparator/outcome of this analysis in your PLE study to see where the problem lies.
