Controlling bias in research.

Bias in clinical research depart the results systematically from the true values due to lack in standardization of protocol.[1] The high demand for publishing articles in the field of academics and acceptance of research that has positive results by the journals has made the researcher to hasten their research, and focus on desirable study outcome. As a consequence, errors in research are becoming inevitable that could be either systematic or random. A random error could be prevented by increasing the sample size, but Bias, a form of systematic error, is difficult to control as multiple factors are involved.[2] Bias can occur in the planning, data collection, analysis, and publication phases of research. Understanding research bias will help in controlling error in research and avoid suboptimal or potentially harmful treatments rendered to the patients/participants.
