Vitamin D With or Without Calcium Supplementation for Prevention of Cancer and Fractures: An Updated Meta-analysis for the U.S. Preventive Services Task Force
Ann Int Med. December 20, 2011 vol. 155 no. 12 827-838
Mixed-effects dose-response meta-analysisでは、10 nmol/L毎、血中25-(OH)Dのどは、6% (95% CI, 3% to 9%) の直腸結腸癌リスク減少と関連。しかし、前立腺癌・乳がんに関しては統計学的用量依存関連が見られなかった。
Random-effects model meta-analysisでは、ビタミンD・カルシウム組み合わせサプリメントにて、高齢者骨折リスク減少(pooled relative risk, 0.88 [CI, 0.78 to 0.99])するも、研究状況にて異なる効果;施設内高齢者(relative risk, 0.71 [CI, 0.57 to 0.89]) v 地域住居高齢者 (relative risk, 0.89 [CI, 0.76 to 1.04])
一つのRCTにて、副作用(腎臓・尿路結石)はサプリメント投与と関連。

多施設ランダム化研究で 第1群はMRI結果を盲目化し、第2群はMRI所見をレビューして治療を決定。
1ヶ月後2群が若干下肢痛スコア低下(mean scores, 3.6 vs 4.4) (P = .12)するも、3ヶ月時点では差を認めず。陽性効果比率は3ヶ月時点で同等 (第1群 35.4% vs 第2群 40.7% )
医師が独立して提案のと異なる注射を受けた第1群においては、画像補正後の患者より下肢痛スコア(4.8 vs 2.4) (P = .01)、機能(38.7 vs 28.2) (P = .04) は劣性であった。
