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
Visit-to-visit variability in systolic blood pressure (VVV-SBP) has been associated with increased cardiac events. Hence, volume analysis by two-dimensional speckle-tracking echocardiography (2-DSTE) allows physicians to easily measure phasic left atrial (LA) function. However, the relationship of VVV-SBP and functional deformation of the left atrium with patients' clinical outcome is unclear. The aim of the study was to investigate the relationship between phasic LA function and VVV-SBP. The subjects were 70 male participants in whom 2-DSTE was performed to measure blood pressure at health check-ups every year for 5 years. The standard deviation of systolic blood pressure (SBP) was calculated to assess VVV-SBP. The average SBP (Ave-SBP) was also assessed. Total emptying function (EF) (reservoir function), passive EF (conduit function), and active EF (booster pump function) of the left atrium were calculated to evaluate phasic LA function by 2-DSTE. The Pearson correlation, simple regression analysis, and multivariate logistic regression analysis were used in data analysis. Participants' mean age was 50 ± 10 years, and 16 participants had hypertension. VVV-SBP correlated with total EF (r = - 0.30, p = 0.014) and active EF (r = - 0.35, p = 0.003). There was no correlation between the standard deviation of SBP and passive EF (r = - 0.10, p = 0.39). Ave-SBP had no significant relationship with total EF (r = - 0.06, p = 0.62), passive EF (r = - 0.08, p = 0.50), or active EF (r = - 0.03, p = 0.78). Active EF was also associated with VVV-SBP in multiple regression analysis. The active EF was significantly decreased in the highest quartile of VVV-SBP. Despite the small sample size of our study, the VVV-SBP showed a relationship with the phasic LA function. Our findings suggest that high VVV-SBP is noted to be associated with cardiovascular risk including a deterioration of LA function in clinical practice.
