Observational studies have a significant role in establishing the prevalence and incidence of diseases in populations, as well as determining the benefits and risks associated with health-related interventions. Observational studies principally encompass cohort, case-control, case series and cross-sectional designs. Inadequate reporting of observational studies is likely to have a negative impact on decision-making in day-to-day clinical practice; however, no reporting guidelines have been published for observational studies in Endodontics. The aim of this project is to develop reporting guidelines for authors when creating manuscripts describing observational studies in the field of Endodontology in an attempt to improve the quality of publications. The new guidelines for observational studies will be named: 'Preferred Reporting items for OBservational studies in Endodontics (PROBE)'. A steering committee was formed by the project leaders (PD, VN) to develop the guidelines through a five-phase consensus process. The steering committee will review and adapt items from the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement and the Clinical and Laboratory Images in Publications (CLIP) principles, as well as identify new items that add value to Endodontics. The steering committee will create a PROBE Delphi Group (PDG), consisting of 30 members across the globe to review and refine the draft checklist items and flowchart. The items will be assessed by the PDG on a nine-point Likert scale for relevance and inclusion. The agreed items will then be discussed by a PROBE Face-to-Face meeting group (PFMG) made up of 20 individuals to further refine the guidelines. After receiving feedback from the PFMG, the steering committee will pilot and finalize the guidelines. The approved PROBE guidelines will be disseminated through publication in relevant journals, and be presented at national and international conferences. The PROBE checklist and flowchart will be available and downloadable from the Preferred Reporting Items for study Designs in Endodontics (PRIDE) website: www.pride-endodonticguidelines.org. The PROBE steering committee encourages clinicians, researchers, editors and peer reviewers to provide feedback on the PROBE guidelines to inform the steering group when the guidelines are updated.

牙髓病学观察性研究（PROBE）指南的首选报告项目：开发协议。

观察性研究在确定人群中疾病的流行率和发病率以及确定与健康相关干预措施相关的益处和风险方面具有重要作用。观察性研究主要包括队列、病例对照、病例系列和横断面设计。观察性研究报告不充分可能会对日常临床实践中的决策产生负面影响；然而，尚未发布关于牙髓病学观察性研究的报告指南。该项目的目的是为作者在创建描述牙髓病学领域观察性研究的手稿时制定报告指南，以提高出版物的质量。新的观察性研究指南将命名为：' 牙髓病学观察研究的首选报告项目 (PROBE)'。项目负责人（PD、VN）成立了一个指导委员会，通过五个阶段的共识过程制定指南。指导委员会将审查和调整来自加强流行病学观察性研究报告 (STROBE) 声明和出版物中临床和实验室图像 (CLIP) 原则的项目，并确定为牙髓病学增加价值的新项目。指导委员会将创建一个由全球 30 名成员组成的 PROBE Delphi Group (PDG)，以审查和完善清单项目和流程图草案。PDG 将根据李克特 9 点量表对这些项目的相关性和包容性进行评估。然后，由 20 人组成的 PROBE 面对面会议小组 (PFMG) 将讨论商定的项目，以进一步完善指南。在收到 PFMG 的反馈后，指导委员会将试行并最终确定该指南。批准的 PROBE 指南将通过在相关期刊上发表的方式进行传播，并在国家和国际会议上发表。PROBE 检查表和流程图可从牙髓研究设计的首选报告项目 (PRIDE) 网站获得和下载：www.pride-endodonticguidelines.org。PROBE 指导委员会鼓励临床医生、研究人员、编辑和同行评审员就 PROBE 指南提供反馈，以便在指南更新时通知指导小组。在收到 PFMG 的反馈后，指导委员会将试行并最终确定该指南。批准的 PROBE 指南将通过在相关期刊上发表的方式进行传播，并在国家和国际会议上发表。PROBE 检查表和流程图可从牙髓研究设计的首选报告项目 (PRIDE) 网站获得和下载：www.pride-endodonticguidelines.org。PROBE 指导委员会鼓励临床医生、研究人员、编辑和同行评审员就 PROBE 指南提供反馈，以便在指南更新时通知指导小组。在收到 PFMG 的反馈后，指导委员会将试行并最终确定该指南。批准的 PROBE 指南将通过在相关期刊上发表的方式进行传播，并在国家和国际会议上发表。PROBE 检查表和流程图可从牙髓研究设计的首选报告项目 (PRIDE) 网站获得和下载：www.pride-endodonticguidelines.org。PROBE 指导委员会鼓励临床医生、研究人员、编辑和同行评审员就 PROBE 指南提供反馈，以便在指南更新时通知指导小组。并在国内和国际会议上发表。PROBE 检查表和流程图可从牙髓研究设计的首选报告项目 (PRIDE) 网站获得和下载：www.pride-endodonticguidelines.org。PROBE 指导委员会鼓励临床医生、研究人员、编辑和同行评审员就 PROBE 指南提供反馈，以便在指南更新时通知指导小组。并在国内和国际会议上发表。PROBE 检查表和流程图可从牙髓研究设计的首选报告项目 (PRIDE) 网站获得和下载：www.pride-endodonticguidelines.org。PROBE 指导委员会鼓励临床医生、研究人员、编辑和同行评审员就 PROBE 指南提供反馈，以便在指南更新时通知指导小组。
