BACKGROUND A few studies have analyzed the role of lifetime anthropometric measures on laryngeal cancer risk. PATIENT AND METHODS This relation was investigated using a multicentre case-control study from Italy, conducted between 1992 and 2000, and including 460 incident, histologically confirmed laryngeal cancer cases, and 1088 controls admitted to the same network of hospitals as cases for ...

Background: Several family structure-related factors, such as birth order, family size, parental age, and age difference to siblings, have been suggested to be risk factors of schizophrenia. We examined how family-structure related variables modified the risk of schizophrenia in Finnish families with at least one child with schizophrenia born from 1950 to 1976. Methods: We used case-sibling des...

A controlled clinical trial was set up. In total 54 subjects of six teams participated and were assigned to either an intervention (IG) or a control group (CG). The IG performed a prescribed balance training p...

The search for multivariate linear regression (MLR) in quantitative structure-property relationships (QSPR) is a hard problem, due to the dimension of the entire search space. A genetic algorithm (GA) was developed and assessed, to select proper descriptors for predicting the octan-1-ol/H2O partition coefficient of polychlorinated biphenyls. The GA was implemented as a Windows based FreePascal ...

In many legal proceedings, fact finders scrutinize the demeanor of a defendant or witness, particularly his or her nonverbal behavior, for indicators of deception. This meta-analysis investigated directly observable nonverbal correlates of deception as a function of different moderator variables. Although lay people and professionals alike assume that many nonverbal behaviors are displayed more...

BACKGROUND It is well known that web-based interventions can be effective treatments for depression. However, dropout rates in web-based interventions are typically high, especially in self-guided web-based interventions. Rigorous empirical evidence regarding factors influencing dropout in self-guided web-based interventions is lacking due to small study sample sizes. In this paper we examined ...
