Impact of early CVP monitoring on 1-year mortality in patients with congestive heart failure in the ICU: a retrospective analysis based on the MIMIC-IV2.2 database.
Article in BMC cardiovascular disorders, 2025. 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
backgroundCentral venous pressure (CVP) monitoring is critical for fluid management in critically ill patients. This study evaluated the impact of CVP monitoring on 1-year mortality in intensive care unit (ICU) patients with congestive heart failure (CHF).
methodsData from the Medical Information for Critical Care IV (MIMIC-IV) database were analyzed for ICU patients admitted for the first time with a stay > 24 h. Patients were categorized into CVP and no-CVP groups based on CVP measurement. Logistic regression analyses were performed, with propensity score matching (PSM) and overlap weighting (OW) to minimize confounding. Inflection point analysis using logistic regression was conducted in the CVP group. Patients were further stratified into early (≤ 24 h) and late (> 24 h) CVP monitoring groups for additional analysis.
resultsAmong 4,479 patients, 919 were in the CVP group and 3,560 in the no-CVP group. CVP monitoring was associated with lower 1-year mortality (odds ratio [OR] = 0.75, 95% confidence interval [CI] = 0.62-0.91, p = 0.003). Early CVP monitoring (≤ 24 h) independently reduced 1-year mortality (OR = 0.68, 95% CI = 0.47-0.97, p = 0.032). Predictors of mortality included the lowest diastolic blood pressure, lowest blood glucose, highest blood chloride, and Acute Physiology Score III (APSIII) score within 24 h of admission.
conclusionEarly CVP monitoring significantly improves 1-year survival in ICU patients with congestive heart failure. These findings underscore the value of timely hemodynamic assessments in critical care and warrant further prospective validation in diverse settings.
