The mean absolute increase in lumbar BMD in the 13 patients in whom the increase was ≥ the LSC, was 0.062±0.036 g/cm 2 resulting in a percent increase from baseline of 7.8±5.9% (range; 2.4-21.5%) and there was a highly significant difference (P<0.0001, power 99.9%) between the pre and post VNS lumbar BMD in these patients.
