Inter-country and inter-method comparisons were done using the Kruskal-Wallis method; correlation coefficients were calculated using Pearson’s rho (r), Bland Altman plots were used to calculate mean differences in findings and 95% limit of agreements (Lo A).
In order to improve clarity, results of all methods were rounded to the nearest full week for scatterplots .
The mean gestational age at delivery using US was 38.7 weeks (95%CI: 38.6–38.8), by LMP, 38.4 weeks (95%CI: 38.0–38.9), by SFH, 38.3 weeks (95%CI: 38.2–38.5), and by BS 38.0 weeks (95%CI: 37.9–38.1) (p This assessment was conducted in the framework of an open label, randomized controlled clinical trial to assess the efficacy and safety of four different artemisinin-combination therapies in women presenting with P.
falciparum malaria in the second and third trimester of pregnancy.
Periodical training was delivered on site by experienced obstetricians and internal QC measures conducted at each site.
This included repeated measurements every first week of the month by the second trained staff member and every third week by repeated measurements of one patient.
At enrolment into the study, patients were asked about the date of their LMP.
LMP was defined as the date of the first day of the last menstruation.
The mean gestational age at delivery using US was 38.7 weeks (95%CI: 38.6–38.8, median: 38.9 weeks, range: 23.1–44.8 weeks), by LMP was 38.4 weeks (95%CI: 38.0–38.9, median: 38.7 weeks, range: 22.9–60.9 weeks), by SFH was 38.3 weeks (95%CI: 38.2–38.5, median: 38.3 weeks, range: 21.1–49.7 weeks) and by BS was 38.0 weeks (95%CI: 37.9–38.1, median: 38.0 weeks, range: 28.0–42.0) (p Correlation between US and any of the other three methods was poor to moderate (LMP: r = 0.38, SFH: r = 0.63, BS: r = 0.31).The gestational age of babies delivered at the hospital was assessed using the BS.Physical and neurological criteria were recorded according to standard guidelines . The combined scores range from − 10 to 50, with the corresponding gestational ages being 20 weeks and 44 weeks (2 week range).Correlation coefficients were calculated using Pearson’s rho, and Bland Altman plots were used to calculate mean differences in findings with 95% limit of agreements.Sensitivity, specificity, positive predictive value and negative predictive value were calculated considering US as reference method to identify term and preterm babies. falciparum infection and a gestational age 24 weeks determined by ultrasound at enrolment were included in the analysis.
