Collection of human genomic DNA from neonates: a comparison between umbilical cord blood and buccal swabs.
Article in American journal of obstetrics and gynecology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo compare DNA yield from neonatal umbilical cord blood and buccal swab specimens. STUDY
designUmbilical cord blood was obtained at birth in a cohort of women enrolled in a preterm labor study. If cord blood was not obtained, neonatal buccal samples were obtained using the Oragene saliva kits. DNA was extracted from all samples using the QIAamp extraction kits. DNA concentration and yield were compared between umbilical cord blood and buccal swabs.
resultsDNA concentrations from umbilical cord blood (n = 35) was greater than that obtained from buccal swabs (n = 20) (total sample: 209.0 ± 110.7 ng/μL vs 6.9 ± 6.7 ng/μL respectively, P < .001; partial sample: n = 30 cord blood vs n = 11 buccal, 70.0 ± 51.4 ng/μL vs 11.3 ± 6.7 ng/μL, respectively, P < .001) and produced more total DNA (total sample: 116.5 ± 70.8 μg vs 4.2 ± 4.0 μg, P < .001; partial:14.0 ± 10.3 μg vs 1.1 ± 0.7 μg, respectively, P < .001).
conclusionBuccal swabs yield less neonatal DNA than umbilical cord blood specimens.
