Fig. 5: Cumulative event risk in C3PO versus Convenience Samples.
From: Cohort design and natural language processing to reduce bias in electronic health records research
Depicted is Kaplan–Meier cumulative risk of MI/stroke (a) and AF (b) observed in C3PO (blue [left] and green [right]) versus the Convenience Samples (red [left] and purple [right]). The number of individuals remaining at risk over time is labeled below each plot. Note an initial rapid inflection in MI/stroke and AF incidence observed in the Convenience Samples but not in C3PO.
