The association between four dietary indices and mortality risk in cardiovascular disease patients.

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
backgroundThe Planetary Healthy Diet Index-United States, the Healthy Diet Index, the Mediterranean Diet, and the Dietary Inflammation Index were linked to mortality rates in cardiovascular patients. This study investigated the relationship between these dietary patterns and all-cause mortality risk in U.S. cardiovascular patients from 2005 to 2006 to 2017-2018.
methodsData were collected from adults aged 19 years and older participating in the National Health and Nutrition Examination Survey from 2005 to 2006 to 2017-2018. Dietary patterns were assessed for each survey cycle using 24-hour dietary recalls, and scores for the four dietary indices were calculated. Survey-weighted multivariable Cox proportional hazards regression models evaluated associations between these indices and all-cause and cause-specific mortality among patients with cardiovascular disease, using hazard ratios across quartiles and per 1-SD increment.
resultsThis study included 3,088 patients with cardiovascular disease. In the partially adjusted model, the Planetary Healthy Diet Index-United States (HR = 0.81; 95% CI: 0.75-0.87; P < 0.001), Healthy Eating Index (HR = 0.85; 95% CI: 0.78-0.93; P < 0.001), and the Mediterranean Diet (HR = 0.82; 95% CI: 0.75-0.90; P < 0.001) were each associated with a reduced risk of all-cause mortality. In contrast, the Dietary Inflammatory Index was associated with an increased risk of all-cause mortality (HR = 1.25; 95% CI: 1.14-1.37; P < 0.001). In the fully adjusted model, the Planetary Healthy Diet Index-United States (HR = 0.89; 95% CI: 0.81-0.97; P = 0.005) remained significantly associated with a lower risk of all-cause mortality, whereas the Dietary Inflammation Index (HR = 1.20; 95% CI: 1.07-1.34; P = 0.002) continued to show a significant association with increased mortality risk.
conclusionsAmong cardiovascular disease patients, higher adherence to the Healthy Eating Index, Mediterranean Diet, and Planetary Healthy Diet Index-United States was linked to lower all-cause mortality, while higher Dietary Inflammation Index scores were linked to increased mortality. The Mediterranean Diet and Planetary Healthy Diet Index-United States were inversely associated with mortality in congestive heart failure patients, whereas Dietary Inflammation Index was positively associated with mortality in this group and in those with angina pectoris.
