Controversy exists regarding the causal relationship between contrast media administration and the development of acute kidney injury because prospective randomized controlled trials (RCTs) confirming this relationship are lacking. In this systematic review we address studies using propensity score matching with regard to contrast-induced acute kidney injury and possible implications for future practice guideline development.

Works about a study where participants are assigned to a treatment, procedure, or intervention by methods that are not random. Non-randomized clinical trials are sometimes referred to as quasi-experimental clinical trials or non-equivalent control group designs.
Clinical trials involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicines, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trials are characterized as RANDOMIZED CONTROLLED TRIALS AS TOPIC.
Clinical trials that involve at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.
Strategy for the analysis of RANDOMIZED CONTROLLED TRIALS AS TOPIC that compares patients in the groups to which they were originally randomly assigned.
Conditional probability of exposure to a treatment given observed covariates.
