Review in International Journal of Cardiology. Hypertension, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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

backgroundManaging blood pressure reduces CVD risk, but optimal treatment thresholds remain unclear as it is a balancing act to avoid hypotension-related adverse events.

objectivesThis systematic review, meta-analysis and meta-regression evaluated the benefits of intensive BP treatment in hypertensive older adults.

methodsWe systematically searched PubMed, MEDLINE, EMBASE, and the Cochrane Library of Controlled Trials until January 31, 2020. Studies comparing different BP treatments/targets and/or active BP against placebo treatment, with a minimum 12 months follow-up, were included. Risk ratios (RR) and 95% CIs were calculated using a random effects model. The primary outcome was RR of major cardiovascular events (MCEs); secondary outcomes included myocardial infarction (MI), stroke, heart failure (HF), cardiovascular (CV) mortality, and all-cause mortality.

resultsWe included 16 studies totaling 65,890 hypertensive participants (average age 69.4 years) with a follow-up period from 1.8 to 4.9 years. Intensive BP treatment significantly reduced the relative risk of MCEs by 26% (RR:0.74, 95%CI 0.64-0.86,

conclusionsLower BP treatment targets are optimal for CV protection, effective, well-tolerated and safe, and support the latest hypertension guidelines.
