Could not create measurementCohort based on BMI

[xihang-chen]

Hi! I am trying to create a cohort with people whose BMI is between 30 and 60. However I wasn't quite able to nail as to what to put in valueAsNumber argument.

Here is my code:

cdm$bmi <- CohortConstructor::measurementCohort(
  cdm = cdm,
  name = "bmi",
  conceptSet = list("bmi" = c(36304833, 3038553)),
  valueAsNumber = list("..." = c(30, 60))
)

So the bmi concept_id I used were 36304833 and 3038553. However I wasn't sure what to put in valueAsNumber argument as unit_concept_id column are all NA for these codes.

This was ran on CPRD GOLD 100k

Maybe we can accept non named list and if that is the case we don't filter "value_as_concept_id" column? Then users can use the function even if that column is NA
