Examining Mother-Reported Poor Sleep and Blood Pressure in Black/African American Mother-Child Dyads.

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
backgroundPoor sleep is a confirmed risk factor for hypertension (HTN), and Black/African American (AA) women have among the highest rates of HTN in the United States.
objectiveWe examined the relationship between sleep and blood pressure (BP) among Black/AA mother-child dyads using data from the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure study.
methodsData for this study were derived from 250 Black/AA mother-child dyads from low-income neighborhoods, collected via 4 home visits over 2 years. Mothers reported poor sleep, including reports of sleeping worse than usual and nighttime awakenings. Recordings of BP were obtained for mother and child. Mother BP was scored as normal (<120/<80 mm Hg), elevated (120-129/<80 mm Hg), stage 1 HTN (130-139/80-89 mm Hg), or stage 2 HTN (systolic ≥140 or diastolic ≥90 mm Hg). Generalized linear models examined the relationships between mother-reported poor sleep variables and both mother and child BP. Adjusted models examining mother BP controlled for the mother's age, education, marital status, smoking, body mass index, and depression symptoms.
resultsIn adjusted models, nighttime awakenings were associated with stage 2 HTN (b = 2.70, 95% confidence interval [CI], 0.54-4.86, P < .05). Compared with children whose mother who had normal BP, children whose mother had elevated BP had higher diastolic BP (b = 0.37; 95% CI, 0.19-0.54; P < .001). Mother elevated BP was associated with both child systolic BP (b = 2.49; 95% CI, 0.44-4.53; P < .05) and diastolic BP (b = 2.07; 95% CI, 0.39-3.76; P < .05). Mother stage 1 HTN was associated with both child systolic BP (b = 2.16; 95% CI, 0.29-4.03; P < .05) and diastolic BP (b = 3.91; 95% CI, 2.40-5.42; P < .001). We detected a significant interaction between mother stage 2 HTN and mother nighttime awakenings in predicting higher child diastolic BP (b = 8.16; 95% CI, 0.65-15.68; P < .05).
conclusionsWe found evidence for an association between mothers' nighttime awakenings and very high BP. Our study also illuminated a strong relationship between high mother BP and high child BP. Finally, our study found preliminary support for the potentially mediating role of mothers' nighttime awakenings in predicting the relationship between mother stage 2 HTN and child BP.
