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 contribute to 14% of all maternal deaths, the majority of which occur in low- and middle-income countries. The aim of the study was to describe the maternal and perinatal clinical outcomes of women with pre-eclampsia living in middle- and low-income countries.

methodsThe study was a prospective observational study of women with pre-eclampsia (n = 1547, 42 twin pregnancies) at three South African tertiary facilities. Using stepwise logistic regression model area under the receiver operating characteristic curve (AUROC) values, the association between maternal baseline and admission characteristics and risk of adverse outcomes was evaluated. Main outcome measures were eclampsia, kidney injury and perinatal death.

resultsIn 1547 women with pre-eclampsia, 16 (1%) died, 147 (9.5%) had eclampsia, four (0.3%) had a stroke and 272 (17.6%) had kidney injury. Of the 1589 births, there were 332 (21.0%) perinatal deaths; of these, 281 (84.5%) were stillbirths. Of 1308 live births, 913 (70.0%) delivered <37 completed weeks and 544 (41.7%) delivered <34 weeks' gestation. Young maternal age (AUROC = 0.76, 95% confidence interval (CI) = 0.71-0.80) and low Body Mass Index BMI (AUROC 0.65, 95% CI = 0.59-0.69) were significant predictors of eclampsia. Highest systolic blood pressure had the strongest association with kidney injury, (AUROC = 0.64, 95% CI = 0.60-0.68). Early gestation at admission was most strongly associated with perinatal death (AUROC = 0.81, 95% CI = 0.77-0.84).

conclusionsThe incidence of pre-eclampsia complications, perinatal death and preterm delivery in women referred to tertiary care in South Africa was much higher than reported in other low- and middle-income studies and despite access to tertiary care interventions. Teenage mothers and those with low BMI were at highest risk of eclampsia. This information could be used to inform guidelines, the research agenda and policy.
