Supporting Evidence (2)

Clinical Trial RegistrationSource: Clinical trial registry (e.g. ClinicalTrials.gov, ISRCTN)

No trial registration found

Assessment Rationale:How INSPECT-AI determined the prospective registration status by comparing dates Registry registration date (study_first_submit_qc_date) is missing or empty.

Study Design EvidenceDates and timelines extracted by INSPECT-AI from the publication text

Recruitment Start: 12-2007

Recruitment Start Rationale:INSPECT-AI's reasoning for how it identified the recruitment start date Materials and Methods: 'A prospective, randomized study was performed from December 2007 to February 2013'; no specific FPI date found, using start of range per rule 5.

Recruitment End: N/A

Recruitment End Rationale:INSPECT-AI's reasoning for how it identified the recruitment end date No explicit end-of-recruitment date found after full search; range end is not used for recruitment_finish.

Study End: 02-2013

Study End Rationale:INSPECT-AI's reasoning for how it identified the study end date Materials and Methods: 'A prospective, randomized study was performed from December 2007 to February 2013'; no specific completion date found, using end of range per rule 5.

Overall — What is the overall integrity assessment of the study?

Automated Assessment:Assessment produced by the automated systemN/A

Human Assessment:Assessment by a domain expert reviewer, informed by AI resultsSome concerns

Rationale: Registration related items are a concern
