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

Background: The systemic immune-inflammation index (SII), a novel inflammatory index integrating neutrophil, platelet, and lymphocyte counts, predicts outcomes in several cardiovascular diseases, yet its role in heart failure with preserved ejection fraction (HFpEF) remains unclear. We therefore investigated the prognostic value of SII in HFpEF patients and compares its performance against other inflammatory markers, including systemic inflammation response index (SIRI), neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP). Methods: We retrospectively analyzed a cohort of 316 patients with HFpEF diagnosed between January 2017 and January 2021. All-cause mortality, cardiovascular mortality and HF rehospitalization were assessed over a median follow-up of 24 months. Net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were employed to evaluate the comparative prognostic performance of SII against SIRI, NLR and CRP. Results: Logistic regression models revealed that each 100-unit increase in SII was independently associated with elevated risks of cardiovascular mortality (OR:1.321, 95% CI:1.191-1.467, P<0.001) and HF rehospitalization (OR:1.168, 95% CI:1.098-1.241, Conclusion: SII emerges as a superior predictor of adverse cardiovascular outcomes in HFpEF compared to conventional inflammatory markers, supporting its use for risk stratification and as a potential therapeutic guide. Nevertheless, its association with all-cause mortality remains limited.
