Associations of Inflammatory Prognosis Index With All-Cause and Cardiovascular Mortality Among Individuals With Diabetes and Prediabetes: A Retrospective Cohort Study.

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
backgroundThe systemic immune-inflammatory index (SII) and the systemic inflammatory response index (SIRI) have shown prognostic value in diabetes mellitus (DM). However, the impact of the inflammatory prognosis index (IPI) remains unexamined. This retrospective cohort study investigates the predictive value of IPI, along with SIRI and SII, on all-cause and cardiovascular disease (CVD) mortality in individuals with DM and prediabetes mellitus (pre-DM).
methodWe analyzed DM and pre-DM individuals from the National Health and Nutrition Examination Survey (NHANES) (1999-2018), with follow-up conducted until December 31, 2019. Cox models assessed the correlation of IPI, SIRI, and SII with mortalities, yielding hazard ratios (HRs) and 95% confidence intervals (CIs). We also utilized restricted cubic spline (RCS) analysis, Kaplan-Meier curves, and subgroup analyses.
resultsThe final analysis included 10,049 individuals with DM and pre-DM. Over a mean follow-up of 9 years, 2233 all-cause mortalities occurred, with 612 attributed to CVD. Fully adjusted Cox regression analysis revealed a significant correlation between continuous and higher tertiles (T3) of IPI, SIRI, and SII and increased risk of all-cause and CVD mortality across all models (all p < 0.05). Kaplan-Meier curves showed higher IPI, SIRI, and SII associated with elevated mortality risk (all log-rank p < 0.001). RCS analysis demonstrated a nonlinear correlation between IPI and all-cause and CVD mortality, as well as between SII and all-cause mortality (nonlinear p < 0.001). However, SIRI exhibited a linear association with both all-cause and CVD mortality.
conclusionElevated IPI, along with SIRI and SII, is linked to increased all-cause and CVD-related mortality in DM and pre-DM, suggesting that incorporating IPI in routine screening could help identify high-risk individuals for earlier interventions.
