Random control test (English: TRIAL, RCT) is a means of detection of some kind of therapy or medicine in medical and health services. It is particularly commonly used in medicine, pharmacy, and nursing research. It is also applied to other areas. The basic method of random control test is to randomly group the research objects and implement different intervention on different groups. The control effect is different under this strict condition. In the case of sufficient number of research objects, this method can offset the impact of known and unknown mixed factors on each group. Random design method: . Complete random design A complete random design (Complete) is also known as group design. The variation between samples is randomly distributed at each processing level, so that the differences in the experimental results can be attributed to the effects of different treatment. This This design assumes that the difference between the subject is balanced by randomization, but in fact, individual differences are often included in the experimental results. If we can exclude these individual differences, the experimental results will be more accurate. . The design of the random zone group The random zone group design (Block), also known as compatible design and compatibility group design, is usually the test object (sample) according to the age, gender, blood pressure of the patient (gender, and blood pressure Non -experimental factors such as weight) are divided into several groups (compatibility groups) of the same or similar), and the test objects (samples) in each group are randomly distributed to different treatment groups, respectively. The design method of the random zone group uses the area group method to separate variants caused by unrelated variables. The method of a balanced experimental group and control group in the same group is actually an extension of pairing design. The main point is to achieve the same quality as possible in the district group, so that the differences in the experimental results to better attribute the effects of different treatment. This design disadvantages of random district groups are required to be equal to the number of test objects in the district group. If there is data in the experimental results, statistical analysis is more troublesome. . The layered random method layered random method (), compared to the simple zone random mechanism. Simple district group random mechanism is to group all test objects. It can only ensure that the test object is divided into two groups according to the size of the overall sample. It cannot guarantee that each group of objects have similar physiological factors (factors) such as gender, age, etc. (generally Not more than three). The grouping random method can realize the physiological characteristics of the two groups of test objects. Specific operations are first or stratified all the subjects in accordance with the specified factors, and then operate the district randomness in each group. Compared with the general district group random method, the group random method is more troublesome, but the physiological characteristics of the two groups are balanced to avoid errors due to non -test factors. The expansion information: The principle of random control test The random control test follows the three principles of random, control and duplicate, and uses statistical knowledge to set a series of research procedures and management measures, Eliminate the subjective impact of doctors and patients on the efficacy of drugs, and achieve a effective comparison with the available drugs that have been listed, and then make a relatively objective evaluation of its effectiveness and safety. Swestern medicine can construct this test method to make a relatively reliable evaluation of the effectiveness and safety of new drugs, which is determined by its inherent theoretical characteristics. It, I will discuss the principles of random control test connotation in conjunction with the theoretical characteristics of western medicine and western medicine. We know that when the random control test is performed and the results are analyzed, the mathematical tool that mainly depends on is statistical knowledge, and the objects handled by statistical knowledge are those independent incidents that can occur repeatedly. It is reflected in medical clinical research that is repetitive. Treatment cases. Reference materials: Baidu Encyclopedia-Random Contracting Test
