Feasibility of multi-component intervention for blood pressure control in pregnancy in Nigeria and Ghana: a pilot randomized clinical trial.

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
backgroundHypertensive disorders in pregnancy are a leading cause of maternal and fetal morbidities and mortalities. They are 5 times as prevalent in Sub-Saharan Africa with relatively higher rate of adverse outcomes. Challenges in management are as a result of physiologic changes in pregnancy, restricted choice of antihypertensives, sub-optimal response to medications in pregnancy and the exclusion of pregnant women from most drug trials. Objectives of this study are to determine the feasibility of delivering multi-component intervention for blood pressure control in women with chronic hypertension in pregnancy, evaluate mean change in systolic blood pressure over the follow-up period, proportion of participants who achieve optimal blood pressure control and the occurrence of adverse maternal and fetal outcomes. METHODOLOGY: This was a pilot multi-center randomized controlled trial involving 60 pregnant women with chronic hypertension in pregnancy randomized into intervention arm (multi-components intervention) and control arm (usual care) in 2 tertiary hospitals in Nigeria and Ghana. Key outcomes were feasibility indices, mean change in blood pressure, proportion of subjects that achieved normal blood pressure, and adverse maternal/fetal outcomes. Data was analysed using Statistical Package for Social Sciences Software (SPSS version 23, 2011, SPSS Inc. Chicago, Illinois). Key feasibility indices were determined, mean difference of blood pressures across all study visits calculated and pairwise comparisons made using Bonferroni correction. Comparison of proportion with uncontrolled BP were made in both study groups. Proportions of Maternal/perinatal outcomes were identified.
resultsRetention rates were 86.7% and 96.7% in Nigeria and Ghana respectively. Mean change in systolic and diastolic blood pressures in the intervention arm from study enrolment to completion was 10.6mmHg (3.1 - 18.1) (p=0.007) and 6.9mmHg (1.9 - 11.9) (p=0.009) respectively. Proportion of participants who achieved optimal blood pressure were comparable between the two groups (20% in the intervention group and 24.1% in the control, p =0.701). Occurrence of adverse maternal/fetal outcomes were comparable in both groups, however, the odds of developing superimposed pre-eclampsia was 27% more in the control group compared to intervention group.
conclusionIt is feasible and acceptable to deliver multi-component intervention for blood pressure control in pregnant women with chronic hypertension in Africa.
