Fig. 3From: Velamentous cord insertion: results from a rapid review of incidence, risk factors, adverse outcomes and screeningIncidence and risk of adverse perinatal outcomes in pregnancies with and without VCI. Numbers in italics were calculated by the review authors. Increased/decreased risk indicates increased/decreased with VCI, respectively. †p value of the odds ratio unless stated otherwise. ‡Unless stated otherwise. §p value for the difference in incidence unless stated otherwise. *Odds ratio calculated by the reviewer. #Weighted number of cases (adjusted for missing data) presented. [a] Adjusted odds ratio. [b] Mean (SD).
