Association between subendocardial viability ratio and cardiovascular events: a cohort study in a Chinese community-based population.
Observational study in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesSubendocardial viability ratio (SEVR) is an effective indicator for evaluating the balance between myocardial oxygen supply and demand. This study aims to explore the association between SEVR and cardiovascular events and mortality in a Chinese community-based population.
designRetrospective cohort study.
settingAn observational cohort established by Peking University First Hospital across multiple communities in China.
participantsA total of 5927 participants without a history of stroke or myocardial infarction (MI) from a Chinese community-based cohort were enrolled. PRIMARY AND SECONDARY OUTCOME MEASURES: SEVR was measured non-invasively using carotid artery pressure waveforms. Participants were divided into low (SEVR<1.3) and high (SEVR≥1.3) SEVR groups. The endpoints included major adverse cardiovascular events (MACEs), comprising all-cause mortality, stroke and MI. Cox proportional hazards models were used to analyse the association between SEVR and endpoints.
resultsThe mean age of participants was 62.12±7.65 years. Over a mean follow-up of 3.23±0.36 years, 207 (3.49%) participants experienced MACE, including 54 (0.91%) deaths, 134 (2.26%) strokes and 38 (0.64%) MIs. After adjusting for risk factors, each one-unit increase in SEVR significantly reduced the risks of adverse cardiovascular events: MACE decreased by 48% (HR 0.52, 95% CI 0.28 to 0.96), all-cause mortality decreased by 71% (HR 0.29, 95% CI 0.08 to 0.99) and stroke decreased by 57% (HR 0.43, 95% CI 0.20 to 0.91). In participants aged≥65 years, higher SEVR was significantly associated with a reduced MACE risk (HR 0.24, 95% CI 0.11 to 0.53).
conclusionsSEVR was an independent predictor of cardiovascular events in this community-based population. Higher SEVR was significantly associated with lower MACE risk, particularly in older adults.
