Introduction
The development of reporting guidelines over the past 20 years represents a major advance in scholarly publishing with recent evidence showing positive impacts. Whilst over 350 reporting guidelines exist, there are few that are specific to surgery. Here we describe the development of the STROCSS guideline (Strengthening the Reporting of Cohort Studies in Surgery).
Methods and analysis
We published our protocol apriori. Current guidelines for case series (PROCESS), cohort studies (STROBE) and randomised controlled trials (CONSORT) were analysed to compile a list of items which were used as baseline material for developing a suitable checklist for surgical cohort guidelines. These were then put forward in a Delphi consensus exercise to an expert panel of 74 surgeons and academics via Google Forms.
Results
The Delphi exercise was completed by 62% (46/74) of the participants. All the items were passed in a single round to create a STROCSS guideline consisting of 17 items.
Conclusion
We present the STROCSS guideline for surgical cohort, cross-sectional and case-control studies consisting of a 17-item checklist. We hope its use will increase the transparency and reporting quality of such studies. This guideline is also suitable for cross-sectional and case control studies. We encourage authors, reviewers, journal editors and publishers to adopt these guidelines.
This study was performed to address the outcomes of patients treated with onlay grafts from the iliac crest to augment the deficient jaw. The results of 173 consecutive patients who underwent bone grafting prior to implant surgery are presented. The grafts were taken from the anterior iliac crest to repair alveolar bone deficiencies that were too large to be corrected using intraoral bone grafts. Three months postoperatively, 869 implants were placed into 190 onlay grafts (167 grafts in the maxilla, 23 in the mandible). The follow-up ranged from 3 months to 23 years post implantation. All patients received a fixed prosthesis. Parameters examined included healing of the donor site and bone grafts, implant survival, peri-implant condition, and donor site morbidity. The overall survival rate for all implants was calculated to be 95% AE 2.7% according to Kaplan-Meier analysis. The implant survival rate compares favourably with those reported in studies using intraoral and extraoral bone.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
