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
Objective: To explore the predictive value of the controlling nutritional status (CONUT) score combined with the systemic immune-inflammation index (SII) for frailty and prognosis in chronic heart failure (CHF) patients with atrial fibrillation (AF). Methods: This retrospective study included 264 patients with CHF and AF who were admitted to and treated at the inpatient and outpatient departments of Nanjing Integrated Traditional Chinese and Western Medicine Hospital from January 2016 to July 2019. Follow-up ended upon patient death, with the final follow-up deadline set for September 2024. Binary logistic regression and Cox regression were used to identify factors influencing frailty and all-cause mortality. The cutoff values for the CONUT score and SII are determined by the ROC diagnostic threshold for mortality. Cutoff values for the CONUT score and SII were 6.5 and 990.2, respectively, categorizing patients into four groups: G1 (high CONUT ≥ 6.5 and high SII ≥ 990.2), G2 (high CONUT ≥ 6.5 and low SII < 990.2), G3 (low CONUT < 6.5 and high SII ≥ 990.2), and G4 (low CONUT < 6.5 and low SII < 990.2). Results: Frailty was present in 165 patients (165/264). Multivariate logistic regression identified disease duration, CONUT score, and SII as significant factors for frailty. A positive correlation between CONUT and SII was observed ( Conclusion: The CONUT score and SII are useful predictors of frailty and mortality in CHF patients with AF. Their combined use may improve the assessment of frailty and prognosis in this population.
