The association between the dietary inflammatory index and multiple myeloma: a case-control study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The dietary inflammatory index (DII) is a common grading system for diet inflammatory potential. Recent investigations link DII to hematopoietic malignancies. However, the relationship between DII and Multiple myeloma (MM) is unknown. DII and MM were examined in a present case-control study of Iranian adults. This case-controlstudy was conducted on adults aged 20 to 75 years, selecting 149 cases with newly diagnosed multiple myeloma and 359 healthy individuals. Dietary assessment was conducted using a validated semi-quantitative food frequency questionnaire (FFQ) including 154 items, and energy-adjusted DII scores were calculated to determine the level of inflammatory properties in each individual's diet using 29 dietary parameters. Conditional logistic regression models were used to investigate the relationship between DII and MM. The case group participating in the study was on average 54 years old and mostly male (52.3%). After adjusting for age, sex, and energy intake, we found that individuals with the highest DII scores were significantly less likely to have MM compared to those with the lowest scores (OR: 0.02; 95% CI 0.01, 0.08). Additional adjustment with other confounders confirmed this association (OR: 0.03; 95% CI 0.01, 0.13). This association did not change significantly with further adjustment for BMI (OR: 0.04; 95% CI 0.01, 0.14). In conclusion, our research showed that a pro-inflammatory diet was associated with a significantly higher risk of MM. If our findings are confirmed in other large studies, these data will provide personalized approaches for MM patients, particularly for physicians and registered cancer dietitians.
