Composite dietary antioxidant index, chronic respiratory disease, and all-cause mortality: National Health and Nutrition Examination Survey, 2003-2018.
Article in European journal of nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeDiet rich in antioxidant may protect against chronic respiratory disease (CRD), but few studies have evaluated the association between composite dietary antioxidant index (CDAI) and CRD. The study aimed to examine the association of CDAI with the risk of CRD and all-cause mortality in CRD patients from the US.
methodsData were obtained from the National Health and Nutrition Examination Survey, 2003-2018. Logistic and Cox regression analyses were used to estimate association of CDAI with CRD and all-cause mortality. Dose-response relationship was examined by restricted cubic spline analyses.
resultsTotal 44,094 participants were eligible for CRD (aged 1-85 years; mean age: 45.71 years old), and 7,685 CRD patients for all-cause mortality (median follow-up: 7.58 years; 1,136 deaths before 12/31/2019). The risk for CRD, asthma, and chronic obstructive pulmonary disease was significantly decreased by 13-32% with the increase intake of CDAI, even after adjusting for confounders (all P < 0.001). The relationship between CDAI and three respiratory endpoints was U-shaped (all P for nonlinearity < 0.001). There was an obvious declining trend in the magnitude of mortality risk with the increase of intake of CDAI, especially in patients with asthma. Fully adjusted hazard ratio was 0.72 (95% confidence interval: 0.54-0.95), 0.55 (0.42-0.72), and 0.48 (0.34-0.66) for the second, third, and fourth quartile of CDAI in patients with asthma relative to the first quartile, respectively. The association with CRD risk was significantly modified by smoking status (P-interaction: 0.006).
conclusionOur findings indicate that high CDAI is a significant protective factor against CRD and all-cause mortality in the US population.
