Data format

The data file should be prepared as a tab-separated file. A decimal point should be used as a decimal separator. Examples of unstratified and stratified data with particular column description are shown below.

Data without stratification factor

If you want to calculate CCI and CLFS estimates for all patients together, your data table should contain following columns:

  • Time from therapy initiation to achievement of the first disease remission (in days)
  • Time from therapy initiation to loss of the first disease remission (in days)
  • Time from therapy initiation to achievement of the second disease remission (in days)
  • ...
  • Follow-up time (time from the therapy initiation to death or to the date of last contact in days)
  • Censoring indicator (1..patient died, 0..patient was censored)

Stratified data

If you want to calculate stratified CCI and CLFS estimates, your data table should contain following columns:

  • Time from therapy initiation to achievement of the first disease remission (in days)
  • Time from therapy initiation to loss of the first disease remission (in days)
  • Time from therapy initiation to achievement of the second disease remission (in days)
  • ...
  • Follow-up time (time from the therapy initiation to death or to the date of last contact in days)
  • Censoring indicator (1..patient died, 0..patient was censored)
  • Stratification factor (maximum number of stratification levels is 9)
