Nettet13. apr. 2024 · We further calculated the threshold inflection point as 57 ml/min/1.73 m 2 using a two-piecewise regression model in Table 3. There was a negative correlation between eGFR and 28-day all-cause mortality on the left of the threshold inflection point, the HR (95% CI) was 0.97 (0.95, 0.99), p < 0.0034. Nettetweights are known. Independent cascade (IC) model and linear threshold (LT) model [19] are two most widely used models to characterize the inﬂuence propagation in a social network, and both models use weights on edges as model parameters. In many real applications, however, the weights are usually unknown in advance. For example, in
