This review aimed to arrange the concepts of a network meta-analysis (NMA) and to demonstrate the analytical process of NMA using STATA software under frequentist framework. The NMA tries to synthesis evidences for a decision making with evaluating the comparative effectiveness of more than 2 alternative interventions for the same condition. Before conducting a NMA, three major assumptions such as similarity, transitivity, and consistency should be checked. The statistical analysis is processed of five steps. First step is to draw a network geometry in order to overview the network relationship. Second step is to check the assumption of consistency using STATA command of . Third step under the consistency is to make the network forest plot or interval plot in order to illustrate the summary size of comparative effectiveness among interventions. Fourth step is to calculate cumulative rankings for identifying a superiority among interventions. Last step is to evaluate publication bias or effect modifiers for a valid inference from results. The synthesized evidences through five steps would be very useful to evidence-based decision-making in healthcare. Thus NMA should be activated in order to guarantee the quality of health care system.

Population genetic and human genetic studies are being accelerated with genome technology and data sharing. Accordingly, in the past 10 years, several countries have initiated genetic research using genome technology and identified the genetic architecture of the ethnic groups living in the corresponding country or suggested the genetic foundation of a social phenomenon. Genetic research has been conducted from epidemiological studies that previously described the health or disease conditions in defined population. This perspective summarizes national genome projects conducted in the past 10 years and introduces case studies to utilize genomic data in genetic research.

Survival analysis of breast cancer patients in three age categories is rare in southern Iran. This paper aims at quantifying prognostic factors contributed to poor prognosis, using Cox and empirical Bayesian additive hazard (EBAH) models among Young (20-39 years), middle (40-64 years) and elderly aged ( over 65 years) women.

There are debates on Kudoa septempunctata as a pathogenic agent causing acute food poisoning because the reproducibility of experimental evidences is in doubt. If K. septempunctata were one of causal agent of acute food poisoning, the more intake of oliver flounder infected by K. septempuctata, the more occurrence of events diagnosed as Kudoa food poisoning. The aim was to evaluate an association between shipping amounts of olive flounder from Jejudo (amounts) and events of Kudoa food poisoning (events).
