bStrength, , counts of pairs that are close in time and space. Cases are close in space if distances between their locations differ by less than 0.5,...,7.5 km. Cases are close in time if dates of diagnosis differ by less than 0.1,...,1.5 year. Nominally statistically significant (P < 0.05) values of S have been emboldened.
