Missing Median

[gargij13]

Hi,
We have encountered an issue where when we run estimateSingleEventSurvival, we do not get the median survival calculated.
recurrent_falls_death <- CohortSurvival::estimateSingleEventSurvival(cdm,targetCohortTable = "recurrent_falls_cohort", targetCohortId = 886, outcomeCohortTable = "death_cohort", strata = list(c("age_group"), c("sex"),c("age_group", "sex")), outcomeDateVariable = "date_of_death", minCellCount =5, followUpDays = followUpDays)
Is there a way we could overcome this?
Thank you,
Gargi

Hi @gargij13, you will only get an estimate for median survival if at least half your study population has the outcome during follow up - do you know if more that half had the outcome in your study follow up?
