Description

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.

Research direction

Start by reproducing the PLE script and capturing the warning text shown in the attached image, along with the generated PS file. Inspect how concepts_to_exclude and createDefaultCovaraiteSettings() are configured, then verify that the warning is resolved and propensity scores are not identical across records.
