Disease and Survival Progression The final analysis was event-powered and performed 8 months after the last patient was signed up for the trial, of which point 327 deaths had occurred , including 10 noncancer deaths and 37 deaths that the cause was unknown. A total of 362 patients had tumor progression , of whom 278 died. Figure 2AFigure 2Outcomes in Patients with Biliary Tract Cancers Who Received Gemcitabine Alone versus Cisplatin plus Gemcitabine.7 months , as compared with 8.1 months for the gemcitabine-only group . Sufferers who received cisplatin plus gemcitabine were 36 percent less likely to die anytime than those that received gemcitabine alone . Adjustment for the randomization stratification factors did not significantly alter this result .The report is on-line.

Among the possible effects of vitamin D insufficiency, the strongest evidence is for a role in skeletal disorders,5,6 but clinical investigations of supplement D supplementation to decrease the chance of fracture have been inconclusive.7-10 Because blacks consistently have lower levels of total 25-hydroxyvitamin D than whites, they are frequently given a medical diagnosis of vitamin D insufficiency.11-13 Yet, as compared with whites, blacks possess higher bone mineral density and a lesser threat of fragility fracture.14-16 Elevated degrees of parathyroid hormone, considered a sensitive marker of vitamin D deficiency often, are more common in blacks than in whites.
