The impact of low dietary inflammatory index diet on clinical parameters in patients with chronic kidney disease: a retrospective comparative study.
Article in BMC nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundChronic kidney disease (CKD) poses a significant global health challenge. Inflammation plays a central role in the pathogenesis and progression of CKD, which has been proved to be affected by dietary patterns. To understand how dietary inflammatory index (DII) impacts the disease course and clinical parameters, we aim to explore the relationship between DII and multiple clinical parameters in a specific cohort of CKD patients, and to provide insights into the potential of dietary for managing CKD.
methodsThis retrospective comparative study included 145 CKD patients, categorized into a low DII group (n = 77) and a high DII group (n = 68) based on their DII values. Clinical data, including demographic characteristics, laboratory parameters, dietary intake, inflammatory markers, renal function, and adverse events, were collected and compared between the two groups.
resultsThe demographic characteristics were comparable between the groups. The low DII group had significantly lower serum creatinine, phosphorus, and potassium levels (P < 0.05) and higher hemoglobin levels compared to the high DII group. Protein intake was significantly higher in the high DII group (P < 0.001), while fiber intake was significantly higher in the low DII group (P = 0.022). Inflammatory markers, including CRP, TNF-α, fibrinogen, procalcitonin, and WBC, were significantly lower in the low DII group (P < 0.05). The low DII group also showed better renal function, as indicated by higher GFR and lower urinary albumin excretion (P < 0.05). Correlation analysis revealed significant relationships between protein intake and inflammation markers (CRP, TNF-α, fibrinogen) and a negative correlation with GFR. Regression analysis confirmed that DII was independently associated with CRP, GFR, and urinary albumin excretion, while protein intake remained significantly correlated with these outcomes.
conclusionA low DII diet may be associated with improved clinical parameters, inflammatory markers, and renal function in CKD patients. Tailored nutritional strategies focusing on modulating inflammatory status through low DII diets may offer promising avenues for improving renal function, mitigating inflammation, and enhancing overall well-being in individuals with CKD.
