From: Comparison of physician networks constructed from thresholded ties versus shared clinical episodes
Distribution of tie survival times for patient-based adaptive networks and episode-based networks (no thresholding), the two of the three approaches studied that result in networks with the same number of edges, making them directly comparable to one another. Proportion of surviving ties would be expected to decrease for survival times 1–5. Ties that have survival times equal to 6 survive throughout the studied period
