Association between red blood cell distribution width and mortality in severe osteomyelitis patients.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Red blood cell distribution width (RDW) is considered to be associated with the prognosis of patients with severe infections. This study aims to investigate the relationship between RDW and prognosis in osteomyelitis patients admitted to the ICU. Through a retrospective cohort study, relevant records of severe osteomyelitis patients were collected from the Medical Information Mart for Intensive Care (MIMIC-IV) database. Patients were divided into low-level and high-level groups based on the median RDW. The primary outcome was the one-year mortality rate of ICU patients. Univariate and multivariate Cox models were used to determine the relationship between RDW and mortality rate in osteomyelitis patients, with hazard ratios (HRs) and 95% confidence intervals (CIs) calculated. Kaplan-Meier survival curves were used to analyze patient survival status. Restricted Cubic Spline (RCS) was used to detect the nonlinear relationship between RDW and mortality rate. Stratified analysis was performed to explore the interaction between different subgroups. The study included a total of 1109 patients, among which 134 (12.08%) died within one year. Results from both univariate and multivariate Cox regression analyses indicated a significant association between elevated RDW levels (HR = 2.128, 95% CI 1.324-3.420) and an increased risk of mortality in patients with osteomyelitis. Kaplan-Meier survival curves demonstrated that the survival time of patients in the low RDW group was greater than that of those in the high RDW group (p < 0.0001). RCS analysis revealed a non-linear increase in the strength of the correlation between patient mortality rate and continuous changes in RDW. Subgroup analysis also observed a relationship between RDW levels and mortality rates in patients with osteomyelitis. Elevated RDW levels are correlated with an increased risk of mortality in osteomyelitis patients admitted to the ICU.
