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

Masked nocturnal hypertension is a hidden blood pressure phenotype in which office blood pressure appears normal or controlled while nighttime ambulatory blood pressure remains elevated. This systematic review evaluated the association between masked nocturnal hypertension or isolated nocturnal hypertension detected by 24-hour ambulatory blood pressure monitoring and cardiovascular or target-organ outcomes in adults with normal or controlled office blood pressure. A systematic search was conducted across PubMed, Web of Science East Mediterranean Region (WOS-EMR), Web of Science, Scopus, and Cochrane Library. Eligible studies included adults with normal or controlled office blood pressure who underwent 24-hour ambulatory blood pressure monitoring and had reported cardiovascular outcomes or target-organ damage. Reviews, editorials, pediatric studies, pregnancy-related studies, studies without nighttime blood pressure data, and studies without relevant outcomes were excluded. Study selection, data extraction, and risk-of-bias assessment were performed using predefined criteria. The included evidence covered population-based cohorts, chronic kidney disease cohorts, diabetes cohorts, hypertension clinic samples, and untreated outpatient populations. Across studies, masked nocturnal hypertension and isolated nocturnal hypertension were generally associated with higher cardiovascular, stroke, and mortality risks, as well as renal, cardiac, vascular, and cerebrovascular target-organ damage, including renal impairment, albuminuria or proteinuria, left ventricular hypertrophy, increased left ventricular mass, arterial stiffness, carotid intima-media thickness, and silent cerebrovascular lesions. However, interpretation should remain cautious because studies differed in population, nocturnal blood pressure thresholds, treatment status, follow-up duration, and outcome definitions. Masked nocturnal hypertension detected by ambulatory blood pressure monitoring appears to be a clinically important phenotype among adults with normal or controlled office blood pressure. The findings support nighttime blood pressure assessment as a useful approach for improving cardiovascular and target-organ risk stratification, especially in high-risk groups such as chronic kidney disease, diabetes, and treated hypertension.
