Recently published papers: A series of negative results

Studies with negative results rarely hit the headlines. But the results are often just as important as the positive ones. A number of 'negative headline' studies are looked at in this review: intensive insulin therapy regime, thrombolysis in cardiac arrest, the effects of nutritional guidelines and rapid response outreach teams.

HYPOTHESIS We hypothesized that review of randomized controlled clinical trials (RCTs) with nonstatistically significant or "negative" results published in the surgical literature do not have appropriate statistical power to demonstrate equivalency between treatment arms. DATA SOURCES AND STUDY SELECTION The MEDLINE database was searched to obtain reports of all RCTs with negative results pub...

Malaria Vaccine Trial Results Are Negative, but Important

Highly active antiretroviral therapy (HAART) for the treatment of individuals infected by HIV-1 is limited by high costs, drug resistance, and drug-related toxicities. This has led researchers to investigate new treatment options, including ways to boost immune responses to better control HIV. One such approach has been termed supervised treatment interruption (STI)—in which HAART is intermitte...

Pnm-19: How Are Prenatal Screening Results after ART Success?

Background Down syndrome screening at first-trimester may cause a higher false positive rate in pregnant patients who have undergone assisted reproductive technologies (ART). Combining the second largest series of biophysical and biochemical tests in the first trimester of pregnancy after ART is mentioned in few studies. MaterialsAndMethods Ghisoni et al explored that NT measurement between ART...
