Metal mixture inflammatory index and mortality risk in chronic kidney disease patients: A nationally representative cohort study from the NHANES 1999 to 2018.
Article in Medicine, 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
Patients with chronic kidney disease (CKD) are frequently exposed to environmental heavy metals, which can easily aggravate the condition or even accelerate death. The association between the metal mixture inflammatory index (MMII) and mortality in CKD patients has not been investigated yet. The MMII was developed using reduced rank regression models to gauge the systemic inflammatory potential of a multi-metal mixture. We analyzed data from 2569 CKD patients who participated in the National Health and Nutrition Examination Survey (1999-2018) with follow-up until December 31, 2019. The association between MMII and mortality was explored via multivariate COX regressions. Patients were divided into 3 groups according to tertiles of MMII: MMII-1 (-0.699 to 0.06), MMII-2 (0.060-0.268), and MMII-3 (0.268-1.329). Compared to MMII-1, the hazard ratios for all-cause, non-cardiovascular disease (CVD), and cancer mortality in MMII-3 were 1.30 (1.01-1.67), 1.49 (1.09-2.03), and 2.44 (1.33-4.49), respectively. In this nationally representative sample of U.S. CKD patients, MMII was closely associated with an increased risk of all-cause, non-CVD, and cancer mortality.
