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
Background: Existing studies have shown the association of circulating vitamin and disease outcome. The study aimed to elucidate individual response of plasma water-soluble vitamins after supplement by PN in critically digestive disorder patients. Methods: We measured the plasma levels of nine water-soluble vitamins (i.e., C, B1, B2, B3, B5, B6, B7, B9, and B12) in consecutive 478 hospitalized critically digestive disease patients receiving identical vitamin-supplemented by PN. Univariate and multifactorial logistic regression analysis were used to evaluated vitamins deficiency and accumulation. The receiver operating characteristic (ROC) curves were used to predict vitamin abnormalities. Furthermore, restricted cubic spline (RCS) was used to analyze the National Health and Nutrition Examination Survey (NHANES) database (2003-2020). Additionally, plasma vitamins levels were contrastive analyzed after PN. Results: There were high prevalence of vitamin C and B9 deficiency (79.71% and 78.45%) but vitamin B2, B5, and B6 accumulation (34.52%, 12.13%, and 11.09%). Multivariate logistic regression analysis revealed that inflammation is an independent risk factor for vitamin C and B9 deficiency, whereas renal dysfunction is an independent risk factor for vitamin B2, B5, and B6 accumulation. The areas under the ROC curves predicting vitamin C, B9 deficiency and vitamin B2, B5, B6 accumulation were 0.80, 0.75, 0.69, 0.79, and 0.89, respectively. The NHANES database further confirms our conclusion. Conventional vitamin supplementation may not efficiently alleviate vitamin C and B9 deficiency in patients with high inflammation, however, it may accelerate plasma vitamin B2, B5, and B6 accumulation with renal dysfunction. Conclusion: Water-soluble vitamin levels were associated with inflammation and renal function. For high inflammation, vitamin C and B9 doses may need to exceed standard levels. In renal impairment, avoid indiscriminate B2, B5, and B6 use; if needed, use alternate-day dosing or lower doses.
