Electrocardiographic tracking of left ventricular hypertrophy in hypertension: incidence and prognostic outcomes from the SPRINT trial.
Article in Clinical hypertension, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01206062 (Systolic Blood Pressure Intervention Trial), which is not on this 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.

Abstract
backgroundThis study explores the impact of intensive blood pressure (BP) control on left ventricular hypertrophy (LVH) incidence and evaluates the prognostic implications of LVH status (pre-existing/new-onset/persistent/regression) using Systolic Blood Pressure Intervention Trial (SPRINT) Electrocardiogram Data.
methodsPoisson regression was used to assess new-onset LVH and LVH regression rates. Multivariable-adjusted Cox proportional hazard models determined the risk of adverse cardiovascular events (ACE), a composite of myocardial infarction (MI), non-MI acute coronary syndrome, stroke, heart failure, or cardiovascular death, alongside safety adverse events.
resultsIn 8,016 participants, intensive BP control significantly reduced new-onset LVH (8.27 vs. 14.79 per 1000-person years; adjusted p<0.001) and increased LVH regression (14.89 vs. 11.89 per 1000-person years; adjusted p<0.001). Elevated ACE risk was notable in participants with pre-existing LVH [adjusted HR: 1.94 (95% CI: 1.25-2.99); p = 0.003], new-onset LVH [adjusted 1.74 (95% CI: 1.16-2.60); p = 0.007], and persistent LVH[adjusted HR: 1.96 (95% CI: 1.11-3.46); p = 0.020], compared to those without LVH. Intriguingly, LVH regression attenuated this risk increment [adjusted HR: 1.57 (95% CI: 0.98-2.53); p = 0.062]. Achieving a BP target of < 120/80 mmHg nullified the increased ACE risk in those with pre-existing LVH.
conclusionsIntensive BP control is instrumental in both reducing the emergence of LVH and fostering its regression. Pre-existing, new-onset LVH and persistent LV remain a predictor of adverse cardiovascular prognosis, whereas LVH regression and achieving on-treatment BP < 120/80 mmHg in pre-existing LVH individuals may further mitigate residual cardiovascular risk.
