""More people are injured by wheelchairs than by lawnmowers, the abstract reports. Bicycles are involved in more accidents than any other consumer product, but beds rank a close second.
""Most of the statistical tables, which come from a variety of government and other sources, are presented raw, without caveats; and because the abstract is so concrete, the statistics can suggest false precision. The table of consumer products involved in injuries does not explain, for example, that one reason nearly as many injuries involve beds as bicycles is that more people use beds."""
