Impact of health literacy and primary language on the decision to pursue trial of labor after prior cesarean delivery.
Trial report in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBoth a trial of labor after cesarean (TOLAC) and elective repeat cesarean delivery (ERCD) are reasonable choices after a cesarean delivery, with differing risks and benefits. This study explores the impact of patient health literacy and primary language on the decision to pursue a TOLAC and on decision quality.
methodsThis is a secondary analysis of the Prior Cesarean Decision (PROCEED) trial, which examined the effect of a patient-centered decision support tool on rates of TOLAC and decision quality. Logistic regression was performed to estimate the association of limited health literacy (Newest Vital Sign score ≤4/6) and non-English primary language (NEPL) with TOLAC. Decision quality was assessed by calculating mean scores for decision-quality scales and using linear regression to estimate adjusted mean differences (aMD) by health literacy and NEPL.
resultsAmong 1455 participants, 44.6% underwent TOLAC, and 71.0% of those with a TOLAC had a vaginal birth after cesarean (VBAC). Limited health literacy was associated with lower odds of TOLAC (aOR 0.60, 95% CI [0.38, 0.93]). For decision quality, limited health literacy was associated with similar scores for decisional conflict, shared decision-making, decision self-efficacy and decision satisfaction, but lower knowledge scores (3.9 vs. 5.4; aMD -0.7, 95% CI [-1.0, -0.5]). Compared to participants whose primary language was English (n=1043), those with NEPL (n=255) had similar odds of TOLAC (aOR 1.08, 95% CI [0.69, 1.68]), but greater decisional conflict (20.9 vs. 16.7; aMD 3.9, 95% CI [1.4, 6.3]) and lower decision self-efficacy (88.6 vs. 90.9; aMD -3.3, 95% CI [-5.6, -1.1]) and decision satisfaction (4.6 vs. 4.7; aMD -0.1, 95% CI [-0.2, 0.0]).
conclusionsIn this study of pregnant people with a prior cesarean and no prior VBAC, those with limited health literacy had lower odds of TOLAC and lower knowledge scores about risks and benefits of TOLAC vs. ERCD. While those with NEPL had similar odds of TOLAC, they had lower decision quality scores compared to those with those with English as a primary language. These findings indicate factors that may result in less effective counseling related to delivery options after prior cesarean and may contribute to differences in approach to delivery and decision quality.
