Association of dietary inflammatory index and Chinese healthy eating index with abdominal obesity in kidney transplant recipients.
Article in Asia Pacific journal of clinical nutrition, 2026. 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
BACKGROUND AND
objectivesThis study investigated associations of the Dietary Inflammatory Index (DII) and Chinese Healthy Diet Index (CHEI) with abdominal obesity in kidney transplant recipients (KTRs), with follow-up analyses further assessing the DII and mortality relationship. METHODS AND STUDY
designWe collected anthropometric and biochemical data; dietary consumption was evaluated using 3-day and 24-hour dietary records, with food quality assessed through energy-adjusted DII (E-DII) and CHEI. Binary logistic regression examined the association between E-DII, CHEI, and abdominal obesity in KTRs. The nonlinear connection between E-DII, CHEI, and abdominal obesity was studied using restricted cubic spline (RCS) analysis. The Kaplan-Meier survival curve was used to examine the survival rate of KTRs.
resultsThe study included 98 KTRs, 34 of whom had abdominal obesity. Logistic regression identified E-DII was a risk factor for abdominal obesity (OR: 5.52, 95%CI:1.19-10.4, p = 0.023), while the CHEI showed protective effects (OR: 0.939, 95%CI:0.893-0.987, p = 0.014). RCS demonstrated a positive linear association between E-DII and abdominal obesity in KTRs (p for overall = 0.042, p for nonlinear = 0.794). In contrast, CHEI exhibited a negative correlation(p for overall = 0.039, p for nonlinear = 0.082). Kaplan-Meier survival curve analysis revealed no statistically significant difference between groups, but the pro-inflammatory group exhibited a 3.8-fold higher mortality rate than the anti-inflammatory group.
conclusionsIn KTRs, elevated E-DII and CHEI levels were associated with abdominal obesity, suggesting that reducing E-DII while increasing CHEI may contribute to its prevention and thus improve long-term survival outcomes.
