Fig. 2.

Forest plots depict agreement between the Boston and PHN z-score models compared by: a age, b sex, and c race. Symbols in the keys represent demographic subgroups, with the location of each symbol along the 83.7% CI denoting CCC point estimates. Differences in levels of agreement between demographic subgroups (e.g., male vs female) were statistically non-significant (p-value > 0.05) if their corresponding 83.7% CI overlapped [13–15]. Asterisks represent the lower limit of the 95% CI, which corresponds to the level of agreement between the Boston and PHN models: < 0.90 indicates poor agreement; 0.90 to < 0.95, moderate; 0.95 to 0.99, substantial; and > 0.99 indicates nearly perfect agreement [9]
