One-hundred four plant species used medicinally by herbalists from three southern Ugandan tribes were collected and identified. The collection includes a large portion of the materia medica of the Abayanda of the southwest region, as well as species used by herbalists of the Baganda and Bakiga Tribes. Literature searches were performed in preparation for further collections, and for collaborati...

Decisions in healthcare should be based on information obtained according to the principles of Evidence-Based Medicine (EBM). An increasing number of systematic reviews are published which summarize the results of prevalence studies. Interpretation of the results of these reviews should be accompanied by an appraisal of the methodological quality of the included data and studies. The critical a...

During the last five years, a number of papers have been published on the statistics of in vitro toxicological assays. Some were directed to the design and analysis of selected single assays (1–6), including an overview report on mutagenicity studies (7) and recommendations for regulatory purposes (8). Others referred to validation studies, frequently performed as interlaboratory studies (9–12).

OBJECTIVE The aim of the present study was to assess the concurrent and construct validity of two diet-quality indices, a modified Mediterranean diet score (mMDS) and a Mediterranean-like diet score (MLDS) additionally incorporating unhealthy food choices, as determined by an FFQ. DESIGN A validation study assessing FFQ intake estimates compared with ten or more unannounced 24 h recalls. Pear...

The development of new methods and approaches to dietary assessment has not kept pace with advances in related disciplines. One of the main gaps is the lack of innovation in incorporating cognitive psychology and computer game technology in developing useful, less biased tools for epidemiologic research on diet and disease. Another problem is the general lack of validation studies imbedded with...

Although in vitro and in vivo experiments have suggested that dietary fiber might have beneficial effects on health, results on the association between fiber intake and all-cause mortality in epidemiologic studies have been inconsistent. Therefore, we conducted a meta-analysis of prospective cohort studies to quantitatively assess this association. Pertinent studies were identified by searching...

BACKGROUND Meta-analysis of randomized controlled trials (RCTs) is usually based on trials where patients are randomized individually into two different, parallel, treatment groups. This paper concentrates on RCTs of a different design-two-period, two-treatment cross-over trials. METHODS The characteristics of these trials are outlined, with detailed examples of methods for analysis for both ...
