4. Dataset sheet "p4" describes a randomized, double-blind, sham-controlled, feasibility and dosing study to determine if a common pulsing electromagnetic field (PEMF) treatment could moderate the substantial osteopenia that occurs after forearm disuse. Subjects were randomized into four groups/treatments, sham, PEMF 1h/day, PEMF 2h/day and PEMF 3h/day. The response measurement is the percent losses in bone mineral density. Each treatment has 20 samples. No Sham PEMF 1h/day PEMF 2h/day PEMF 3h/day 1 4.51 5.32 4.73 7.03 7.95 6 5.81 4.65 4.97 5.12 5.69 6.65 3 7.08 3.86 5.49 DO - a UI A W N 7.97 5.48 4.06 6.98 2.23 6.52 6.56 4.85 3.95 4.09 8.34 7.26 5.64 6.28 3.01 5.92 9.35 7.77 6.71 5.58 10 6.52 5.68 6.51 7.91 4.96 8.47 1.7 4.9 12 6.1 4.58 5.89 4.54 13 7.19 4.11 6.55 8.18 14 4.03 5.72 5.34 5.42 15 2.72 5.91 5.88 6.03 16 .19 6.89 7.5 7.04 17 5.17 6.99 3.28 5.17 18 5.7 4.98 5.38 7.6 19 5.85 9.94 7.3 7.9 20 6.45 6.38 5.46 7.91 (a).
