Anxiety and Arterial Stiffness in High-Risk Pregnancies: A Secondary Analysis of a Prospective Cohort Study.

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
objectivesIn a high-risk pregnant population with singleton pregnancies, the primary objective was to evaluate the association between anxiety and arterial stiffness (AS) and the secondary objective was to investigate whether anxiety is associated with the incidence of preeclampsia.
designSecondary analysis of a prospective cohort study (2012-2016).
settingTwo tertiary care antenatal clinics in Montreal, Canada.
participantsHigh-risk pregnant individuals with pre-existing hypertension, diabetes, renal dysfunction, previous preeclampsia, or age ≥ 35 years were included. Exclusion criteria were excessive alcohol or drug use and cardiovascular disease. People with pregnancy loss, incomplete questionnaires and loss to follow-up were excluded from analysis.
methodsParticipants were enrolled before 14-weeks' gestation, with follow-up assessments of AS every 4 weeks until delivery. Anxiety symptoms were assessed every trimester by the Beck Anxiety Inventory and by self-reported history of emotional disorders (anxiety/depression).
main outcome measuresAS and wave reflection parameters, primarily carotid-femoral pulse wave velocity and preeclampsia diagnosis.
resultsOf 235 individuals recruited, 161 were included in this secondary analysis. Baseline anxiety symptoms were present in 35.4% of participants. Anxiety was associated with a significant increase in carotid-femoral pulse wave velocity across gestation, which persisted after adjustments for relevant confounders, in a combined mixed-effects model (B = 0.27, 95% confidence interval [CI] = 0.008-0.530, p = 0.04). A severity-response relationship was observed, where greater anxiety severity correlated with higher AS. Twelve participants (7.5%) developed preeclampsia. The association between anxiety and preeclampsia risk showed a non-significant trend (odds ratio [OR] = 2.77, 95% CI = 0.84-9.18). However, a history of emotional disorders significantly elevated preeclampsia risk (OR = 3.91, 95% CI = 1.14-13.40), independent of other risk factors.
conclusionsAnxiety in high-risk pregnancies is associated with increased AS in a severity-response manner, and may be associated with preeclampsia risk. Integrating psychological health assessments with traditional obstetric evaluations could enhance the prediction and management of maternal complications.
