Nighttime Systolic Blood Pressure Determined by Pulse Transit Time Predicts Cardiac Events in Patients With Heart Failure.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe optimal systolic blood pressure (SBP) target for heart failure (HF) patients has not been established. Although the association between daytime SBP and prognosis has been reported in patients with HF, the prognostic impact of nighttime SBP remains unclear.
methodsWe conducted continuous nighttime SBP measurements noninvasively using pulse transit time in 366 patients with HF (median age, 72 years; male sex, 195), and followed up for cardiac events (HF hospitalization or cardiac death). Average values of nighttime pulse transit time -based SBP were used in the present study. The patients were divided into tertile groups based on nighttime pulse transit time-based SBP: high-SBP group (median SBP, 136 mm Hg; n=122), middle-SBP group (median SBP, 117 mm Hg; n=122), and low-SBP group (median SBP, 100 mm Hg; n=122).
resultsDuring a median follow-up period of 1083 days after nighttime pulse transit time-based SBP measurement, 71 patients experienced a cardiac event. Kaplan-Meier analysis showed the highest incidence of cardiac events in the low-SBP group. Multivariate Cox proportional hazard analysis also showed that the lowest SBP tertile was associated with a higher risk of cardiac events compared with the highest SBP tertile as reference (hazard ratio, 2.100 [95% CI, 1.121-3.933];
conclusionsLow nighttime SBP was associated with an increased cardiac event rate in patients with HF.
