Observational studyJornal brasileiro de nefrologia
Dietary inflammatory index in patients with chronic kidney disease under conservative treatment at a university hospital in Rio de Janeiro, Brazil.
Observational study in Jornal brasileiro de nefrologia. 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
introductionChronic kidney disease (CKD) is associated with a chronic low-grade inflammatory state, which may be influenced by dietary patterns. The Dietary Inflammatory Index (DII) is a validated tool used to estimate the inflammatory potential of the diet.
objectiveTo evaluate the dietary inflammatory potential in patients with CKD undergoing conservative treatment and its association with anthropometric and cardiovascular risk markers.
methodsA cross-sectional observational study was conducted in adult patients diagnosed with stage 3-5 CKD under conservative management. Dietary intake was assessed using two non-consecutive 24-hour dietary recalls, and DII scores were calculated based on 36 dietary parameters. Anthropometric and cardiovascular risk indicators were evaluated, including body mass index (BMI), triceps skinfold thickness (TSFT), arm muscle area (AMA), waist-to-height ratio (WHtR), Castelli indices, and the conicity index (CI). Multivariate linear regression models were adjusted for age, sex, and estimated glomerular filtration rate (eGFR).
resultsA total of 51 patients were included, with a median age of 71 years (IQR, 56-80), and 56.9% were female. The median DII score was 2.90 (IQR, 2.29-3.74), indicating a predominantly pro-inflammatory dietary profile. Higher DII scores were associated with higher conicity index values (β = 0.368; p = 0.010). No statistically significant associations were observed between the DII and other anthropometric, biochemical, or cardiovascular risk markers.
conclusionPatients with CKD under conservative treatment exhibited predominantly pro-inflammatory dietary patterns. Higher DII scores were associated with greater central adiposity.
