Extract data for bayesian meta analysis of survival data. From your description it sounds more like a study of incidence rates where you have the number of events and the person-time in each group. For survival analysis you would usually need the observation time for each person. I.

Data Extraction and Analysis: Individual patient-level data were collected for each of 628 study patients. Multi-variable Cox proportional-hazards regression was used to estimate the effect of induction therapy on allograft survival.

Currently, Progression Free Survival (PFS. and also encouraged sponsors to discuss details of the meta-analysis prior to submission, more specific guidance would be useful on the minimum data.

Background: (Network) meta-analysis of published survival data are often based on the reported hazard ratio, which relies on the proportional hazards assumption. This assumption is implausible when hazard functions intersect and can result in invalid indirect treatment comparisons and network meta-analysis of competing interventions.

Are Evolution And Natural Selection The Same In the 1920s and 1930s the so-called modern synthesis connected natural selection and population genetics, based on Mendelian inheritance, into a unified theory that applied generally to any branch of biology. The modern synthesis explained patterns observed across species in populations, through fossil transitions in palaeontology, and complex cellular mechanisms in developmental biology.
