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

Hypertensive disorders of pregnancy (HDP) are the predominant pregnancy complication in both high and low-middle-income countries. The age-standardized incidence rate and the absolute incidence number of HDP in low-middle-income countries are 2-fold and 4-fold higher than in high-income countries in 2021, respectively. However, the reduction in the age-standardized prevalence rate (-41.1% vs. -8.7%) and incidence rate (-40.8% vs. -7.1%) of HDP is ≈5-fold faster in low-middle income countries compared with high-income countries between 1990 and 2021. Moreover, HDP is significantly associated with the increased risk of adverse perinatal outcomes, including preterm birth, low birth weight, and perinatal mortality in both high and low-middle-income countries. In the current review, we have highlighted the prevalence, incidence, and temporal trend of HDP and its association with adverse perinatal outcomes in high and low-middle-income countries.
