That’s correct, @Chungsoo_Kim that inclusion rules don’t alter the index dates (beyond disqualifying them for inclusion into the cohort)…but i also wanted to point out that the definition above has the following behavior:
- Find all events of High Blood Pressure that occurred before 2018-06-30
- Filter those events to the earliest event per person note: this is from the 'limit initla events to earliest event per person
- For each cohort entry event (remember: this is just 1 per person now), include that event in the cohort if it had prior flu
- Select the earliest event per person from the remaining events note, this is from the bottm 'limit qualifying events to earliest event per person’
Sometimes, this is the desired behavior: you only want to let the earliest event be considered for inclusion criteria before any other inclusion rules are applied. But, if that isn’t what is desired here, then you need to change one of the settings: if you want to consider all high Blood Pressure events that occurred before 2018-06-30 for the Flu inclusion rules, but in the end you just want to have one event per person, then you should change the top ‘limit cohort entry events’ to be ‘all events per person’, and leave the lower ‘limit qualifying events’ to ‘earliest per person’.
