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

Background: A significant gap exists in understanding the efficacy and safety of oral immediate-release nifedipine and intravenous hydralazine in the control of severe hypertension in pregnancy within the context of randomised control trials. Objectives: To compare the efficacy and safety of oral immediate-release nifedipine and intravenous hydralazine for controlling severe hypertension in pregnancy. Methods: Randomised, double-blind, 2-arm, single center non-inferiority trial in pregnant women with confirmed severe hypertension in pregnancy who were randomised in a 1:1 ratio to receive oral immediate-release Nifedipine (n=35) or intravenous hydralazine (n=35) was done from 20 Results: The baseline socio-demographic parameters were similar between the two groups. The mean durations taken to reach the target blood pressure for patients that received oral immediate-release nifedipine versus intravenous hydralazine were 48.29min±31.95 and 41.20min±26.98 respectively (P=0.320). The mean dose used before target blood pressure was reached, the proportion of participants that crossed over to another treatment allocation, and the proportion that required a rescue antihypertensive (labetalol) to achieve the target blood pressure were similar between the two groups (P >0.05). None of the participants that received oral immediate-release nifedipine had maternal or neonatal side effect while one participant (2.9%) that received intravenous hydralazine had nausea and vomiting. Conclusion: Oral immediate-release nifedipine is as effective as intravenous hydralazine in controlling severe hypertension in pregnancy. Both have remarkable materno-fetal safety profile and its non-invasive nature makes it an appealing modality especially in resource poor countries. More robust studies are encouraged to increase the evidence for its use as first line antihypertensives, especially in low and middle-income countries.
