This will improve research transparency and will ultimately strengthen the validity and value of the scientific evidence base. The registration of all interventional trials is a scientific, ethical and moral responsibility.展开更多

Design and Methods: The present study is a cross-sectional study using data from clinical trials registered from January 1, 2011, to December 31, 2015. Only countries with more than 2000 registered trials were included for further study. Ten countries met that criterion: United States, Japan, Iran, Australia, New Zealand, China, India, Germany, United Kingdom, and Netherland. The percentage of clinical trials that were registered in each country’s registry was calculated, and the factors determining that percentage were sought and analyzed through an exploratory approach. Results: The chi-squared test of independence indicated that the rate of clinical trial registration significantly differed between countries. From the adjusted standardized residuals, the percentage of clinical trials that were registered in the country of origin was higher in the United States, India, Japan, and Australia/New Zealand than in the European Union and China. Conclusion: The United States requires that informed consent documents for clinical trials contain clinical trial registration numbers from ClinicalTrials.gov, which could be the reason for the extremely high percentage of registered clinical trials (94%). Since the European Union does not have this requirement, clinical trials conducted in the European Union do not have to be registered in the countries in which they are conducted.展开更多

Since the early 1970 s it has been known that diabetics display higher values of Hb_(A1c) because they have elevated blood glucose concentrations. Thus Hb_(A1c) has acquired a very important role in the treatment and diagnosis of diabetes mellitus. After the introduction of the first quantitative measurement of Hb_(A1c), numerous methods for glycohemoglobin have been introduced with different assay principles: From a simple minicolumn technique to the very accurate automated highpressure chromatography and lastly to many automated immunochemical or enzymatic assays. In early days, the results of the quality control reports for Hb_(A1c) varied extensively between laboratories, therefore in United States and Canada working groups(WG) of the Diabetes Controls and Complications Trial(DCCT) were set up to standardize the Hb_(A1c) assays against the DCCT/National Glycohemoglobin Standardization Program reference method based on liquid chromatography. In the 1990 s, the International Federation of Clinical Chemistry and Laboratory Medicine(IFCC) appointed a new WG to plan a reference preparation and method for the Hb_(A1c) measurement. When the reference procedureswere established, in 2004 IFCC recommended that all manufacturers for equipment used in Hb_(A1c) assays should calibrate their methods to their proposals. This led to an improvement in the coefficient of variation(CV%) associated with the assay. In this review, we describe the glycation of Hb, methods, standardization of the Hb_(A1c) assays, analytical problems, problems with the units in which Hb_(A1c) values are expressed, reference values, quality control aspects, target requirements for Hb_(A1c), and the relationship of the plasma glucose values to Hb_(A1c) concentrations. We also note that the acceptance of the mmol/mol system for Hb_(A1c) as recommended by IFCC, i.e., the new unit and reference ranges, are becoming only slowly accepted outside of Europe where it seems that expressing Hb_(A1c) values either only in per cent units or with parallel reporting of percent and mmol/mol will continue. We believe that these issues should be resolved in the future and that it would avoid confusion if mmol/mol unit for Hb_(A1c) were to gain worldwide acceptance.展开更多
