Recalculation of the numbers at risk - example classified as "consistent". Kaplan-Meier plot of a randomised trial comparing prednisolone and a control group
[4]. According to the information in the text of the publication, one patient was lost
to follow-up in the prednisolone group and minimum follow-up was 120 days. At one
time point beforehand (90 days), we read the survival probability from the curve (see
vertical line). We recalculated the number of patients at risk by multiplying the
survival probability with the number of randomised patients (number at risk: 17 in
the prednisolone group vs. 6 in the control group). As the calculated and reported
numbers matched (taking into account the one patient lost to follow-up in the prednisolone
group), this example would be classified as "consistent".
