Differences between cochrane systematic evaluation and traditional review

The differences between cochrane systematic reviews and traditional reviews are as follows:

The purpose is different: traditional reviews are to collect and summarize the literature for the next step of scientific research, whereas systematic reviews are to comprehensively summarize a problem and evaluate whether a current intervention is effective or not.

Systematic reviews (systematic reviews) is a newly developed or reconstructed system, according to the predetermined system objectives, using the method of system analysis, from the technical, economic, social, ecological and other aspects of the system design of the various programs for review and selection, in order to determine the optimal or sub-optimal or satisfactory system program.

There is no uniform model of system evaluation due to the differences in social systems, resource conditions, economic development status, education levels and national traditions of various countries. Evaluation projects, evaluation standards and evaluation methods are also different.

Prior evaluation in the planning stage of the evaluation, this time because there is no actual system, generally can only refer to existing information or simulation methods for predictive evaluation, and sometimes also with the bidding and voting methods, the synthesis of people's intuitive judgment and evaluation.

Intermediate evaluation in the plan implementation stage of the evaluation, focusing on testing whether the implementation in accordance with the plan, for example, the evaluation of the project progress with the plan coordination techniques.

After-the-fact evaluation is conducted after the system is implemented, i.e., after the project is completed, and evaluates whether the system has achieved the desired goals. Because the performance of the actual system can be measured, it is easier to make an evaluation. Qualitative evaluation of social factors related to the system can also be conducted by surveying the opinions of people who have contact with the system.
