Forest plot (unweighted) of the area under the curve (AUC) and 95% confidence intervals (CI) of included studies assessing models that did not include FIT as a variable, subgroup is by outcome aimed to predict. Where models were validated, these scores are used in the forest plot. ˆdenotes a development and validation model; ∗denotes a validation only model. If no denotation, the model was development only. Studies that do not have confidence intervals did not report dispersion data. Abbreviations: AUC = Area Under the Curve; CI = Confidence Interval; CRC = Colorectal Cancer; AA = Advanced Adenoma; HRA = High Risk Adenoma.
