1 · What the graph read from 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.

2 · The registry

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

backgroundHypertensive disorders of pregnancy (HDP) are associated with short-term cardiac structure and function abnormalities, but later life changes are not well studied.

objectivesThis study aimed to determine if HDP history is associated with echocardiographic differences 8 to 10 years after delivery, and if subgroups with placental maternal vascular malperfusion (MVM) lesions or current hypertension may be particularly affected.

methodsWomen with pregnancies delivered from 2008 to 2009 were selected from a clinical cohort with abstracted pregnancy and placental pathology data to undergo transthoracic echocardiography (2017 to 2020). Medical history, blood pressure, and weight were measured at the study visit.

resultsThe authors enrolled 132 women (10 ± 1 years post-delivery, age 38 ± 6 years): 102 with normotensive pregnancies and 30 with HDP: pre-eclampsia (n = 21) or gestational hypertension (n = 9). Compared with women with normotensive pregnancies, those with HDP history were more likely to have current hypertension (63% vs. 26%; p < 0.001). After adjusting for age, race, MVM lesions, body mass index, current hypertension, and hemoglobin A1c, women with HDP history had higher interventricular septal thickness (β = 0.08; p = 0.04) and relative wall thickness (β = 0.04; p = 0.04). In subgroup analyses, those with both HDP history and current hypertension had a higher proportion of left ventricular remodeling (79.0%) compared with all other groups (only HDP [36.4%; p = 0.01], only current hypertension [46.2%; p = 0.02], and neither HDP nor hypertension [38.2%; p < 0.001]), and lower mitral inflow E/A and annular e'. Accounting for placental MVM lesions did not impact results.

conclusionsWomen with both HDP history and current hypertension have pronounced differences in left ventricular structure and function a decade after pregnancy, warranting continued surveillance and targeted therapies for cardiovascular disease prevention.
