Characteristics Associated With Consent and Reasons for Declining in a Randomized Trial in Pregnancy.
Trial report in Obstetrics and gynecology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01990612 (Induction in Nulliparous Women at 39 Weeks to Prevent Adverse Outcomes), which is not on this map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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.

Abstract
objectiveTo evaluate the maternal characteristics associated with consent to a randomized trial of labor induction in pregnancy.
methodsThis is a secondary analysis of low-risk nulliparous women randomized to induction of labor at 39 weeks or expectant management. During the trial, the Data and Safety Monitoring Committee requested additional fields on the screening log, which already included race and ethnicity: maternal age, type of insurance, and the reason for declining consent if declined.
resultsFrom August 2016 (start of additional data collection) to August 2017, 1,965 (28%) of the 7,112 eligible women consented to the trial. Consent was more likely for Black women (41%, adjusted odds ratio [aOR] 1.47, 95% CI 1.24-1.74), and less likely for Asian women (15%, aOR 0.64, 95% CI 0.48-0.84), compared with White women (24%). Women without private insurance were more likely to consent (38%, aOR 1.55, 95% CI 1.34-1.79), compared with those with private insurance (22%). Younger women were also more likely to consent. Among eligible women who declined participation and provided a reason (68%), preference to be expectantly managed (85%) was most common, a response more common in Asian women (aOR 1.75, 95% CI 1.31-2.33) and less common in women without private insurance (aOR 0.60, 95% CI 0.51-0.70). Not wanting to participate in research was more common in Asian women (aOR 2.41, 95% CI 1.44-4.03). Declining consent because family or friends objected was more common in Asian women (aOR 2.51, 95% CI 1.27-4.95) and women without private insurance (aOR 1.68, 95% CI 1.10-2.59).
conclusionFrequency of consent and reasons for declining consent were associated with age, type of insurance, and race and ethnicity. These findings should be considered when developing recruitment strategies that promote diverse participant representation. CLINICAL
