Body fat monitors: Information in a chart accompanying a Health section article Monday about body fat monitors was inadvertently cut off. The chart used dunk tank and caliper tests to compare body fat readings on five devices with two clinical tests that gave readings of 18% and 21%. The Omron Body Logic device should have showed 20.1% body fat, not 20%. The Omron Full Body Sensor should have indicated 20.7% body fat, not 20%. The Tanita UMO61 should have listed 20.9%, not 20%. The information should have been credited to the Washington Post.
