Tabular displays of data are a critical element in quantitative medical research. Tables that are effective and properly constructed are likely to increase the chances of acceptance for publication. Nevertheless, previous research indicated that tables included in published medical articles were not presented optimally. This article, based on general requirements of medical journals, outlines the basic elements of a typical table and explains its design and content. In the final stage of table construction, careful proof reading must be done to ensure it is free of errors and the style matched with that required by the journal. Furthermore, every table in an article should be self-explanatory that the main message of the table can be understood without consulting the main text. Based on our suggestions, readers should gain a better understanding of how to construct tables that can concisely and accurately represent the results of a study.
