Circulating 25-hydroxyvitamin D level and prognosis of lung cancer patients: A systematic review and meta-analysis

摘要

Background > Previous studies suggested a possible influence of circulating 25-hydroxyvitamin D [25(OH) D] level on the prognosis of lung cancer patients, but conflicting findings were reported. A systematic review and meta-analysis was thus conducted to comprehensively assess the influence of circulating 25(OH) D level on the prognosis of lung cancer patients.
