Data provided as n (%).
↵* Differences in size associated with category were assessed through ordinal regression of office size category (from Table 1) on ownership type or HIT stage. Reported P values are adjusted for multiple comparisons (Tukey).
↵† Implementation stages were averaged for 5 capabilities as described in the text.
