Dietary carotenoids and acute respiratory infection in the general US population: NHANES 2003 - 2018.

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
backgroundWe aimed to investigate the association between dietary carotenoids and acute respiratory infection (ARI) in the general US population.
methodsWe analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2003 - 2018 and 64,560 participants with complete records of dietary intake and ARI definition. Five major dietary carotenoids were evaluated: α-carotene, β-carotene, lycopene, β-cryptoxanthin, and lutein plus zeaxanthin. Survey-weight logistic regression and restricted cubic spline were applied.
resultsThe relationship between dietary carotenoids and ARI risk followed a linear trend. Participants in the highest quartile of dietary carotenoid intake exhibited a 15% lower risk of ARI than those in the lowest quartile (multi-adjusted odds ratio [OR]: 0.85, 95% confidence interval [CI]: 0.72 - 0.99). Individually, the association with ARI was consistently significant for β-carotene (multi-adjusted OR, 95% CI: 0.82, 0.69 - 0.98), β-cryptoxanthin (0.77, 0.66 - 0.91), lycopene (0.86, 0.75 - 0.99), and lutein plus zeaxanthin (0.84, 0.71 - 0.99). There was a significant inverse relationship between total carotenoid intake and ARI among children aged 1 - 18 years(multi-adjusted OR, 95% CI: 0.74, 0.57 - 0.97 for the highest quartile, and 0.78, 0.63 - 0.96 for the third quartile compared with lowest quartile).
conclusionsIn this US national general population, our findings indicated that higher dietary carotenoid intake was inversely associated with ARI risk.
