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

backgroundHypertension is one of the most common medical conditions complicating pregnancy, and is a major contributor to maternal, fetal and neonatal morbidity and mortality in Canada.

objectivesTo determine the incidence and trends of gestational hypertension among pregnant women in the Calgary Health Region of Alberta.

methodsGestational hypertension was classified according to current published Canadian guidelines: without proteinuria and with proteinuria. Hospital discharge abstracts were used to identify women diagnosed with gestational hypertension in the Calgary Health Region between January 1995 and December 2004. The Birth Registry of Vital Statistics was used to determine the number of live births and stillbirths in the Calgary Health Region during the study period. Incidence was calculated with 95% CIs. Age-standardized gestational hypertension rates were calculated using 2004 live births and stillbirths as the reference.

resultsOver the 10-year period, the incidence of nonproteinuric gestational hypertension was relatively stable even after age adjustment, with an average incidence of 6.3% (95% CI 6.1% to 6.4%). When gestational hypertension was stratified by age, women aged 35 years or older had an almost twofold higher incidence of both nonproteinuric and proteinuric gestational hypertension than those younger than 35 years of age.

conclusionsInterventions to prevent and improve the management of gestational hypertension, particularly among women aged 35 years and older, are required.
