Supporting Evidence (2)
Clinical Trial RegistrationSource: Clinical trial registry (e.g. ClinicalTrials.gov, ISRCTN)
Registration ID: NCT00803959
Registry: ClinicalTrials.gov
Registry Link: https://clinicaltrials.gov/study/NCT00803959 (opens in new tab)
Registration Date: 05-12-2008
Prospective:Whether the trial was registered before participant recruitment began No
Assessment Rationale:How INSPECT-AI determined the prospective registration status by comparing dates Comparison performed at month level. Registration: 2008-12, LLM Recruitment Start: 2008-11. Deemed retrospective at month level.
Study Design EvidenceDates and timelines extracted by INSPECT-AI from the publication text
Recruitment Start: 11-2008
Recruitment Start Rationale:INSPECT-AI's reasoning for how it identified the recruitment start date Results: 'Between November 2008 and June 2010, a total of 630 women underwent randomization' - using start of enrollment range as recruitment start date, no specific FPI date found.
Recruitment End: 06-2010
Recruitment End Rationale:INSPECT-AI's reasoning for how it identified the recruitment end date Results: 'Between November 2008 and June 2010, a total of 630 women underwent randomization' - no specific LPI date found, using end of enrollment range as recruitment finish date.
Study End: N/A
Study End Rationale:INSPECT-AI's reasoning for how it identified the study end date No explicit study completion date found.
Overall — What is the overall integrity assessment of the study?
Rationale: It appears there are some concerns regarding registration and attention to detail in some papers by the authors.
