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

objectivesTo identify the key points for improving severe maternal morbidity by analyzing pregnancy-related ICU admissions in Beijing.

designThis was a retrospective, multicenter cohort study.

settingThree ICUs in tertiary hospitals in Beijing. PATIENTS: A total of 491 severe maternal cases in any trimester of pregnancy or within 42 days of delivery were reviewed between January 1, 2008, and December 31, 2016.

interventionsNone. MEASUREMENTS AND MAIN

resultsAmong 491 obstetric ICU admissions (median Sequential Organ Failure Assessment score, 2) out of 87,850 hospital deliveries (a frequency of 5.6 admissions per 1,000 deliveries), the leading diagnoses were postpartum hemorrhage (170; 34.62%), hypertensive disorders of pregnancy (156; 31.77%), and cardio-cerebrovascular diseases (78; 15.9%). Comparing 2008-2011 to 2012-2016, the rates of maternal mortality (2.5% vs 1.9%; p = 0.991) and fetal loss (8.5% vs 8.6%; p = 0.977) did not decrease significantly, whereas the rates of ICU admission (3.05% vs 7.85%; p trends < 0.001) and postpartum hemorrhage (23% vs 38.5%; p = 0.002) increased. Hypertensive disorder (150/156; 96.2% transferred to the ICU postpartum, 24/28 women with fetal loss transferred from lower-level hospitals) was an independent maternal factor associated with fetal loss, and infections were the leading cause of maternal death (6/10) in the ICU.

conclusionsOur study highlights the increasing rate of intensive care admissions for postpartum hemorrhage. Improving prenatal care quality for pregnancy-induced hypertension and sepsis at lower-level hospitals may improve maternal and fetal outcomes. Specifically, providing more effective regional cooperation before transfer and shifting patients who require continuous surveillance but not necessarily intensive care to a transitional ward in a tertiary hospital would provide more ICU beds for more prenatal intensive care for the most complex medical conditions.
