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

objectiveTo evaluate temporal trends in use of antihypertensive medications during delivery hospitalizations complicated by preeclampsia and risk of maternal stroke over the same time period.

methodsThe Perspective database was used to perform a retrospective cohort study evaluating antihypertensive drugs dispensed during delivery hospitalizations complicated by preeclampsia from 2006 to the first quarter of 2015. Medications evaluated included nifedipine, hydralazine, and oral and intravenous labetalol. Adjusted models for receipt of antihypertensive agents accounting for demographic and hospital factors were created. Hospital-level rates of antihypertensive administration for women with severe preeclampsia were analyzed. Risk of stroke during delivery hospitalization was evaluated.

resultsA total of 239,454 patients with preeclampsia were included in the analysis including 126,595 women with mild, 31,628 with superimposed, and 81,231 with severe preeclampsia. Overall, 105,409 women received a hypertensive agent. From 2006 to 2014, for all patients with preeclampsia, receipt of oral labetalol increased from 20.3% to 31.4%, intravenous labetalol from 13.3% to 21.4%, hydralazine from 12.8% to 16.9%, nifedipine from 15.0% to 18.2%, and more than one medication from 16.5% to 25.8%. The proportion of patients with preeclampsia receiving any antihypertensive medication rose from 37.8% in 2006 to 49.4% in 2015. In adjusted models, temporal trends retained significance. Rates of antihypertensive administration for severe preeclampsia varied significantly by hospital. For severe preeclampsia, the risk for stroke decreased from 13.5 per 10,000 deliveries in 2006-2008 (n=27) to 9.7 in 2009-2011 (n=25) to 6.0 in 2012-2014 (n=20) (P=.02).

conclusionUse of multiple antihypertensive agents to treat preeclamptic women increased over the study period for women with mild, superimposed, and severe preeclampsia. There was substantial hospital variation in use of antihypertensive agents. This trend was associated with decreased risk of maternal stroke.
