Hepatocyte growth factor and risk of incident stroke in Black and White Americans in the Reasons for Geographic and Racial Differences in Stroke study.
Article in Research and practice in thrombosis and haemostasis, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Hepatocyte growth factor (HGF) is a cytokine produced in response to endothelial damage. Higher levels correlate with cardiovascular risk factors, including hypertension and diabetes. Objectives: We hypothesized that HGF is associated with stroke. Methods: The Reasons for Geographic And Racial Differences in Stroke (REGARDS) study enrolled 30,239 Black and White Americans aged ≥45 years from 2003 to 2007. In this case-cohort study, after 5.5 years of follow-up, circulating baseline HGF was measured in 557 participants with incident ischemic stroke and in a cohort random sample of 964 participants. Hazard ratios (HRs) per SD log-transformed HGF and by HGF quintile were calculated using Cox proportional hazards models adjusting for stroke risk factors and other correlates of HGF. Differences by race and sex were tested using interaction terms. Results: Median HGF was 295 (IQR, 209-402) pg/mL. HGF was higher with older age, male sex, prevalent cardiovascular disease, smoking, and warfarin use, but did not differ by race. The adjusted HR of incident ischemic stroke per SD higher baseline HGF (145 pg/mL) was 1.30 (CI, 1.00-1.70), with no difference by sex or race. HGF in the highest (>434 pg/mL) vs lowest quintile (<135 pg/mL) was associated with an adjusted HR of incident stroke of 2.12 (CI, 1.31-3.41). Conclusion: In the REGARDS study, higher HGF was associated with increased risk of incident ischemic stroke in Black and White adults, with a doubling in risk of HGF in the top quintile compared with the lowest quintile after adjusting for other stroke risk factors.
