An L-shaped link between the composite dietary antioxidant index and human papillomavirus infection in women: a US population-based study.

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
Objective: This study intended to inspect the link between a comprehensive dietary antioxidant index (CDAI) and human papillomavirus (HPV) infection in US women. Methods: The link between CDAI and HPV infection was analyzed by weighted univariate and multivariate regression models, restricted cubic spline (RCS), and subgroup analyzes using the NHANES data from 2003 to 2016. Results: Data from 8,115 subjects were included, with a weighted prevalence of HPV infection of 38.01%. After adjusting for all covariates, HPV infection decreased by 2% for each 1-unit rise in CDAI [(95%CI: 0.96, 0.99), Conclusion: CDAI is negatively linked to HPV infection. American women can enhance their intake of antioxidant-rich foods, especially those rich in zinc and vitamin E, to reduce HPV infection risk and enhance antioxidant defenses.
