Literature reviews are a valuable source of information; by locating, appraising and synthesising evidence from primary studies they can provide reliable answers to focused questions. They can also help to plan new research by identifying both what is known and not known in a given area. Literature reviews adhere to a scientific methodology which seeks to minimise bias and errors generating inferences based on the synthesis of best available evidence.
