“…When the height was documented in feet, it was converted to stories in increments of 12 ft (ie, 0 -12 ft ϭ first story, 12.1-24 ft ϭ second story, and Ն24.1 ft ϭ third story or higher), on the basis of methods used in previous studies. 7,10,12 Landing surfaces were categorized as hard surfaces (including concrete, asphalt, pavers, and bricks), firm surfaces (including grass, gravel, dirt, roofs, and decks and balconies not specified as concrete), soft surfaces (including bushes, mulch, bark, and flowerbeds), and other surfaces. Window status before the fall was coded as open, screened, closed (including windows that do not open), or other (eg, plastic or cardboard in the window or window guard in place).…”
