Improving Patient Knowledge of Aneuploidy Testing Using an Educational Video: A Randomized Controlled Trial.
Trial report in Obstetrics and gynecology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 evaluate the effectiveness of an educational video explaining aneuploidy testing.
methodsThis was a randomized controlled trial of women with singleton pregnancies having aneuploidy testing at less than 14 weeks of gestation from September 2016 to March 2017 at our prenatal ultrasound center. We developed an educational video on aneuploidy testing. Participants, stratified by age younger than or 35 years or older at estimated delivery date, were randomized to either view or not view the video before their ultrasonogram. Participants 35 years or older also met with a genetic counselor at the ultrasound appointment. All participants completed a survey assessing knowledge of genetic testing (score of 0-15) at baseline and after the appointment. The primary outcome was change in knowledge score after the intervention. A sample size of 23 per group (n=92) was planned for a total of 46 women younger than 35 years of age and 46 women aged 35 years or older. Data are presented as median (interquartile range).
resultsOf 104 eligible women who were approached, 92 were randomized. Forty women aged younger than 35 years and 41 women aged 35 years or older completed the study. Baseline characteristics were similar across groups. In women younger than 35 years, the video group had a significant improvement in knowledge score (+2.0 [1.0-5.0]) compared with the control group (0 [-1.0 to 1.0]; P=.01) and reported better understanding of the information compared with the control group (P<.001) with no change in patient satisfaction (P=.25). In women 35 years or older, change in knowledge score was similar for the video and control groups (P=.98) with no difference in self-reported understanding (P=.49) or patient satisfaction (P=.30).
conclusionA patient-centered educational video explaining aneuploidy testing options improved knowledge and self-reported understanding of the information in women younger than 35 years with no change in patient satisfaction. No difference was seen for women 35 years or older, likely as a result of genetic counseling provided to these women.
