publications with 26 prediction models were included in this review.10-34 Cross- referencing yielded no additional results. The characteristics of 26 prediction models (Shen et al. reported two models)34 are summarised in Table 1. Four publications were adaptions of earlier published prediction models.35-38

There was some heterogeneity between the study cohorts and related interventions; patient cohorts included patients with colorectal cancer and patients with colorectal surgery (including those with noncancer indications). The most frequently studied intervention was resectional colorectal surgery; in the study of
