Reporting of the items of the TRIPOD statement overall (a) and per type of prediction model study (b) (see Box 1 for list of items of the TRIPOD statement). NA not applicable (not all items of the TRIPOD statement are relevant to all types of prediction model studies). Percentages are based on number of models for which an item was applicable (and thus should have been reported). *Where this number deviates from the total number of models, this is indicated. This concerns the following items (N = number of models for which the item was applicable). Overall: 5c (N = 169), 10a (N = 127), 10b (N = 127), 10c (N = 84), 10e (N = 23), 11 (N = 70), 12 (N = 81), 13c (N = 97), 14a (N = 127), 14b (N = 94), 15a (N = 127), 15b (N = 127), 17 (N = 7), 19a (N = 92); Development: 5c (N = 72), 11 (N = 22), 14b (N = 55); External validation: 10e (N = 8), 11 (N = 15), 17 (N = 4); Incremental value: 10c (N = 20), 10e (N = 11), 11 (N = 20), 12 (N = 17), 14b (N = 25), 19a (N = 29); Development and external validation: 10e (N = 4), 11 (N = 13), 14b (N = 14), 17 (N = 3), 19a (N = 20). †Item 21 ’Provide information about the availability of supplementary resources, such as study protocol, Web calculator, and data sets’: the number of models for which this item was applicable is unknown. It probably was applicable to all models that reported this item. Instead of presenting a percentage of 100, we based the percentage on the total number of models.
