Association Between the Red Blood Cell Distribution Width-to-Albumin Ratio, Nursing Notes, and the Length of Hospital Stay in Iron Deficiency Anaemia Complicated With Congestive Heart Failure Patients.
Article in Nursing open, 2026. 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
aimsTo evaluate the influence of the red blood cell distribution width-to-albumin ratio (RAR) and sentiment scores from nursing notes on the length of hospital stay (LOS) and mortality risk among iron deficiency anaemia (IDA) patients with congestive heart failure (CHF).
designA retrospective study.
methodsData for this retrospective research were obtained from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Multivariable logistic regression analysis was conducted to determine the individual associations of RAR and sentiment subjectivity scores with 7-day hospital LOS. Additional multivariable logistic analyses and subgroup analyses were performed to explore the joint effect of RAR and subjectivity combined on 7-day hospital LOS.
result655 IDA patients with CHF were included. Among them, 384 patients (58.63%) had a hospital LOS exceeding 7 days. Multivariable logistic regression revealed that the RAR and the scaled subjectivity were linked to the 7-day hospital LOS. The combination of RAR and subjectivity was significantly associated with the 7-day hospital LOS. Compared to the low subjectivity and low RAR group, the group with high subjectivity and high RAR was identified as a risk factor for a 7-day hospital LOS.
conclusionHigh RAR and high subjectivity were associated with a higher risk of 7-day hospital LOS in IDA patients with CHF, but the two predictors did not interact. Prospective validation of RAR-based risk stratification and of joint RAR-subjectivity classification as an exploratory descriptive tool is warranted before clinical implementation. IMPLICATIONS FOR PATIENT CARE: Nurses may use RAR and nursing note subjectivity as complementary information to identify patients at higher risk of prolonged hospitalisation and prioritise nursing assessment and care planning accordingly. REPORTING
methodAdhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.
