Abstract：
Prognostic models provide an avenue to predict the risk of individual patients and support shared-decision making. Many prognostic models are published annually, and systematic reviews provide an avenue to collate the existing evidence behind prognostic models to determine whether a model demonstrates adequate predictive performance and is ready for real-world use. This article provides a brief step-by-step guide on how to conduct a systematic review and meta-analysis of prognostic model studies and how these reviews differ from systematic reviews of therapy and diagnosis.
摘要：
预后模型为预测个体患者的风险和支持共同决策提供了途径。许多预后模型每年出版，和系统评价提供了一个途径来整理预后模型背后的现有证据，以确定一个模型是否表现出足够的预测性能，并准备好在现实世界中使用。本文简要介绍了如何对预后模型研究进行系统评价和荟萃分析，以及这些评价与治疗和诊断的系统评价有何不同。
