Association between the Naples Prognostic Score and the Charlson Comorbidity Index in peritoneal dialysis patients.

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
This study aimed to investigate the association between the Naples Prognostic Score (NPS) and the Charlson Comorbidity Index (CCI) and to evaluate the relationship of NPS with inflammatory and nutritional status in patients undergoing peritoneal dialysis (PD). A total of 59 PD patients (mean age 41.8 ± 18.1 years, 30 females) who received PD between 2020 and 2025 were retrospectively analyzed. NPS was calculated using serum albumin, total cholesterol, neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR), and patients were classified into NPS groups. Comorbidity burden was assessed using CCI. Group comparisons and correlation analyses were performed to determine associations between NPS, clinical variables, laboratory parameters, and CCI. The mean NPS and CCI were 2.80 ± 1.21 and 3.71 ± 2.21, respectively. Patients with higher NPS had significantly longer dialysis duration and elevated markers of systemic inflammation, including C-reactive protein, neutrophils, and monocytes, whereas they showed lower lymphocyte counts, lymphocyte-to-monocyte ratio, LDL cholesterol, and total cholesterol (all
