Sex differences in adherence to highly active antiretroviral therapy
Bias
The concept of bias is the lack of internal validity or incorrect assessment of the association between an exposure and an effect in the target population in which the statistic estimated has an expectation that does not equal the true value. Biases can be classified by the research stage in which they occur or by the direction of change in a estimate. The most important biases are those produced in the definition and selection of the study popul…
Participation of epidemiologists and/or biostatisticians and methodological quality of published controlled clinical trials
METHODS Quality variables, abstracted from a review, were related to authors' specialties. Five hundred and ninety four CCTs were identified via a hand search. The department/unit membership was used to attribute authors' specialties. Of 594 CCTs identified, in 127 the authors' specialties could not be known, leaving 467 trials for analysis
Recreation in coastal waters
STUDY OBJECTIVE: To find out whether bathing in sewage polluted waters implies a danger to bathers' health and to determine the best microbiological indicator to predict the relation between bathing and the appearance of some symptoms. DESIGN: Cohort study. SETTING: City of Santander (north of Spain). PARTICIPANTS: From the people going to four Santander beaches in the period from 1 July to 16 September 1998, a cohort of 2774 persons was recruite…
Age differential mortality in Spain, 1900-1991
STUDY OBJECTIVE: To analyse the interindividual inequalities in mortality in Spain through the 20th century using the Gini coefficient, widely used as an income concentration index. DESIGN: Age mortality data were obtained from official publications of vital statistics and age and sex compositions were obtained from population census. The Gini coefficient was estimated. It can take values between 0 and 1. Zero represents the situation in which al…
