Abstract

Twenty-six female patients were recalled for examination 10 years after a Roux-Y gastric bypass (RGB) procedure for morbid obesity, to determine whether there was biochemical and/or bone densitometry evidence of metabolic bone disease. These patients were compared with seven control patients who had achieved weight loss by dietary restriction. The serum calcium (4.3 +/- 0.03 vs 4.6 +/- 0.06 mEq/l; p = 0.002) was decreased in the RGB group. Both the serum alkaline phosphatase level (121.0 +/- 7.6 vs 87.3 +/- 8.3 U/I; p = 0.018) and the serum osteocalcin (12.6 +/- 1.2 vs 9.5 +/- 1.9 µg/ml; p = 0.078) level increased in the RGB group. The 1,25(OH) vitamin D level (50.5 +/- 2.5 vs 40.5 +/- 4.9 pg/ml; p = 0.152) was similar for both groups; the 25(OH) vitamin D level (24.3 +/- 1.6 vs 35.9 +/- 3.4 ng/ml; p = 0.008) was decreased in the RGB group as compared with the control group. Bone mineral density was elevated in three of the lumbar measurement sites, and marginally decreased (0.90 +/- 0.02 g/cm(2) vs 1.03 +/- 0.06 g/cm(2); p = 0.067) in the femoral neck of the RGB group compared with the controls. This biochemical pattern suggests the development of metabolic bone disease following the RGB.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Spine BMD changes after RYGB are variable, with some studies reporting small decreases and others not.

    “Changes at the spine are more variable, some studies report small decreases 24, 54, 63, 67-69, while others have not 52, 53, 65, 66.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
