Power Law scaling parameter and tests of fit for selected distributions by minimum value of contacts included in analysis

PCOOH primary care out-ofhours (service), ED emergency department

Alpha represents the scaling parameter of the power law probability distribution p(x) ∝ x^−α

KS Kolmogorov-Smirnoff test for fit of data to power law, reported as p value (value > 0·05 indicates no difference between data and power law)

Vuong Better fitting distribution to the data by Vuong test (p values in blue indicate that the power law was the better fitting distribution, p values in red that the log-normal was the better fit
