Regression analysis is an important statistical method for the analysis of medical data. It enables the identification and characterization of relationships among multiple factors. It also enables the identification of prognostically relevant risk factors and the calculation of risk scores for individual prognostication. ⋯ The performance and interpretation of linear regression analysis are subject to a variety of pitfalls, which are discussed here in detail. The reader is made aware of common errors of interpretation through practical examples. Both the opportunities for applying linear regression analysis and its limitations are presented.

Review Meta Analysis
Midclavicular fracture: not just a trivial injury: current treatment options.
Conservative treatment was long recommended for midclavicular fractures because of the excellent results that were reported in the 1960's and 70's. Recently, however, the rucksack bandage has received competition from surgical treatment. The spectrum of operations ranges from classic plate osteosynthesis to intramedullary techniques and angle-stable implants. ⋯ In any case of midclavicular fracture, the type of fracture should be precisely analyzed and an individual treatment strategy should be developed in view of the patient's particular situation. Current studies show with a high level of evidence (level 1) that patients with dislocated fractures benefit from surgery.
