Use of Antihypertensive Medications and Uterotonics During Delivery Hospitalizations in Women With Asthma.
Article in Obstetrics and gynecology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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 estimate whether the diagnosis of asthma is associated with the use of specific uterotonic and antihypertensive medications during delivery hospitalizations.
methodsWe used Perspective, an administrative database, to determine whether women hospitalized for delivery complicated by postpartum hemorrhage or preeclampsia received uterotonics and antihypertensive medications differentially based on the absence or presence of asthma from 2006 to 2015. Given that carboprost and intravenous (IV) labetalol may be associated with asthma exacerbation, adjusted models for receipt of these medications were created with adjusted risk ratios with 95% CIs as measures of effect. Risk for status asthmaticus based on receipt of carboprost and IV labetalol was analyzed.
resultsOver the study period, a total of 5,691,178 women were analyzed, of whom 239,915 (4.2%) had preeclampsia and 139,841 postpartum hemorrhage (2.5%). Carboprost was used less frequently in patients with asthma compared with patients with no asthma (11.4% vs 18.0%) in comparison with IV labetalol, which was used more commonly when a diagnosis of asthma was present (18.5% vs 16.7%). In unadjusted analysis, the presence of asthma was associated with a 37% decrease in likelihood of carboprost use and an 11% increase in likelihood of labetalol use. In adjusted analysis, the presence of asthma was associated with a 32% decrease in likelihood of carboprost use (adjusted risk ratio 0.68, 95% CI 0.62-0.74) compared with a 7% decrease in labetalol use (adjusted risk ratio 0.93, 95% CI 0.90-0.97). Risk for status asthmaticus was significantly increased with use of IV labetalol compared with other antihypertensive medications (6.5 vs 1.7/1,000 delivery hospitalizations, P<.01).
conclusionThere may be an opportunity to reduce use of β-blockers and carboprost among patients with asthma. Given their association with status asthmaticus, these drugs should be used cautiously in women with asthma.
