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

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological entity initially described in 1996. PRES frequently develops in patients with preeclampsia and eclampsia. There is not much literature on risk factors causing PRES in pregnant patients with eclampsia. This study aimed to determine the incidence of PRES in eclampsia, its association with pregnancy, risk factors, and maternal and perinatal outcomes. PATIENTS AND

methodsAll patients who were admitted with eclampsia and developed PRES in an intensive care unit of a tertiary medical facility between 1997 and 2017 were included in the study. Patients' demographics, pregnancy and gestational data, treatment mode, and outcomes were retrospectively obtained from their medical charts/files. Data were entered using SPSS program version 23. Chi-square test was used to compare the variables, and a

resultsA total of 151 patients were admitted during the study period, and 25 developed PRES. The diagnosis was common in patients older than 25 years. Eclampsia patients who developed PRES were without any pregnancy-associated comorbidities (

conclusionOf eclampsia patients, 16% developed PRES, which is on the lower side than the reviewed literature (10%-90%). Eclampsia on presentation, recurrent seizures, postpartum eclampsia, cesarean delivery, and labetalol use were associated with increased risk of PRES development.
