Hypertensive disorders of pregnancy in low- and middle-income countries: a review of antenatal interventions to improve maternal outcomes.

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
Introduction: Hypertensive disorders of pregnancy remain a major contributor to maternal mortality worldwide, responsible for an estimated 16% of maternal deaths with the majority in low- and middle-income countries (LMICs). This review synthesizes interventions for HDP tailored to LMICs to improve their widespread implementation and in turn, improve maternal outcomes. Methods: This review synthesizes literature published between 2010 and 2024 on interventions addressing hypertensive disorders of pregnancy in LMICs using MEDLINE, Cochrane, EMBASE, and WHO Global Index Medicus. Interventions are described using a novel conceptual framework establishing three key steps of the hypertension disorders of pregnancy care continuum: prevention, screening, and treatment. Results: A total of 212 studies were identified with interventions across multiple domains: 21 involved (10%) screening, 51 (24%) prevention and 119 (56%) treatment, and 21 (10%) including more than one step. The majority of studies were from lower-middle- and middle-income countries, with less than 10% including only low-income countries. Interventions range from educational programs, clinical trials evaluating medication type and dosing algorithms, and development of novel screening tools with comparably little implementation science studies. Discussion: The majority of studies on interventions for hypertensive disorders of pregnancy in LMICs were randomized trials focused on efficacy. While there were several feasibility and acceptability studies, there was a lack of research translating trials to real-world community and clinical settings. Further, interventions were lacking in countries with the highest rates of maternal mortality. Additional research should focus on the implementation of integrated strategies that improve care across all stages of the care continuum, particularly in LMICs with the greatest burden.
