Prognostic Nutritional Index (PNI) in Patients With Diabetes and Sepsis: A Cross-Sectional 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
BACKGROUND AND
objectivesSepsis and multiorgan dysfunction syndrome (MODS) are serious global health concerns. Patients with critical illnesses are assessed using the sequential organ failure assessment (SOFA) score for morbidity. The prognostic nutritional index (PNI) is a novel composite biomarker for sepsis. It is based on two parameters: absolute lymphocyte count and serum albumin. The purpose of this study was to examine PNI in patients with diabetes and sepsis. Additionally, we correlated the SOFA score and PNI of the study participants at admission.
methodsThis cross-sectional study was carried out from August 2025 to December 2025 at the Kalinga Institute of Medical Sciences (KIMS), Bhubaneswar, India. Adult diabetes patients of both sexes fulfilling Sepsis-3 criteria were included in this study. We recorded their absolute lymphocyte count and serum albumin for PNI calculation. SOFA scores were noted at day 1, 3, and 7. The categorical and continuous variables were assessed with the Chi-square and the Wilcoxon test, respectively. We used the Spearman correlation to assess the association between the SOFA score at day 1 and the subjects' PNI values. R software (version 4.3.2) was used for data analysis.
resultsA total of 557 patients were assessed in this study. Their median age was 59.0 (52.0-65.0) years. Of the participants, 335 (60.14%) were male. The average hospital stay was 12.0 (9.0-16.0) days. MODS was recorded in 459 (82.41%) patients. The median serum albumin and absolute lymphocyte count of the study population were 2.80 (2.40-3.20) g/dL and 1.13 (0.69-1.88) x 10
conclusionMale and female subjects with sepsis had comparable PNI values. However, serum albumin, absolute lymphocyte count, and SOFA scores showed statistically significant differences between genders. The PNI and SOFA scores were negatively correlated. The majority of the subgroup analyses also showed weakly negative associations. However, the study findings cannot be generalized due to a single-centric design, a small sample size, and missing data on hemodynamic, renal, hepatic, and glycemic parameters, antibiotics used, daily fluid intake, urine output, comorbidities, and concomitant medications.
