METHODS: Using ISI Web of Science database for statistical sources, we retrieved DR literatures during 2000-2010, analyzed 'the number of published articles per year, authors, source publications, subject category, document type, document language, institution and country/region' by bibliometric statistical methods. RESULTS: The total number of published articles that were retrieved for the years during 2000-2010 was 8590. DR researches changed as a linear upward trend, the main researches focused on ophthalmology, endocrine and metabolic diseases. Article was the main document type. Harvard University was the major research institution. CONCLUSION: There has achieved a significant increase in the number of ISI publications and collaborations in DR literatures from 2000 to 2010. With the rising of the number of diabetes in the world, diabetic retinopathy has become a focus of scientific researches.展开更多

The present research uses a scientometric technique to examine secondary literature. Between 2000 and 2015, 871literature by Bangladeshi writers and 3,71,389 literature by worldwide authors on PH were retrieved from the Scopus database and evaluated using quantitative indicators to study growth and development from various perspectives. The highest growth in terms of the number of publications has been observed in the year 2015(133) and the lowest in 2001(10). The PR(Percent of Growth Rate) shows that 2001 was the deepest decreasing year(-38%) whereas 2002was the most increasing year(90%). During the study, RGR(Relative Growth Rate) values of Bangladeshi contributions to PH literature varied from 0.16 to 0.55, with an average of 0.27. The CC(Collaborative Coefficient) value indicates that during the research period, there was a substantial amount of collaboration among the authors. At the same time, the PPA(Productivity Per Author) value(0.31) denotes that throughout the era, each Bangladeshi author produced less than half of a publication per year. The mean Activity Index(AI) during 2000-2015 was 89.14,which reflects lower activity than the world’s average in PH literature. It was also observed that research productivity in public health of Bangladesh follows Lotka’s inverse rule of author production. According to the findings, there is a strong link between public health research output in emerging and developed nations.展开更多
