What makes a good format: frameworks for evaluating the effect of graphic risk formats on consumers' risk-related behavior.

The format in which risk information is presented has a fundamental influence on the quality of risk communication with health consumers.

Based on a review of literature within and outside the medical domain, we present four useful frameworks for evaluating the effects of graphic format on risk-related behavior.
