Effects of Different Systolic Blood Pressure Targets on Myocardial Function: A One-Year Follow-Up in Geriatric Hypertension.
Article in International journal of general medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundA lower systolic blood pressure (SBP) target reduces major cardiovascular events and mortality from any cause of geriatric hypertension. However, the effect of different SBP targets on myocardial function remains unclear. This study aimed to determine changes in left ventricular (LV) strain in older hypertensive patients after 1 year of different SBP goals, and to evaluate its effects on myocardial mechanics in this population.
methodsWe studied 313 hypertensive adults aged 60 years or older after 1 year of the Systolic Blood Pressure Intervention Trial. They were divided into the intensive group (target SBP: 110-130 mmHg) and the standard group (target SBP: 130-150 mmHg). All participants underwent echocardiography within 1 week after enrollment and 1 year after participating in the study. Global longitudinal strain (GLS) of the LV (endocardial, middle, and epicardial layer: GLS-end, GLS-mid, and GLS-epi, respectively) and the improvement of GLS at 1 year (ΔGLS-end, ΔGLS-mid, and ΔGLS-epi) were measured.
resultsAt 1 year, GLS-end in the intensive group was slightly improved compared with that before the trial (-23.78%±3.10% vs -22.58%±3.11%, P<0.05). The ΔGLS-end and ΔGLS-mid in the intensive group were higher than those in the standard group (1.20±0.23 vs 0.58±0.59% and 0.70±0.21 vs 0.52±0.17, P<0.05). Moreover, SBP at 1 year and an angiotensin II type 1 receptor antagonist were independent factors that affected ΔGLS-end (β= -0.005, P=0.004; β= 0.080, P<0.001, respectively).
conclusionThese trial results suggest that a lower SBP target can slightly improve myocardial function in older hypertensive patients at 1 year.
