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
Although the benefits of enhanced nutrition on respiratory health are widely recognized, the specific effects of vitamins B6 and B12 on lung function are not fully understood. This study aimed to investigate the potential association between vitamin B6 and B12 intake and lung function. This is a cross-sectional study using data from the National Health and Nutrition Examination Survey from 2007 to 2012. The study assessed the pulmonary function of the subjects by measuring forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio. In addition, stepwise multiple linear regression, logistic regression modeling, and other analytical methods were used in this study in order to investigate the correlation between vitamin B6 and B12 intake and lung function. A total of 9648 participants were included in this study, and after adjusting for relevant confounders, linear regression analyses showed that for every 1 mg/day increase in vitamin B6 intake, there was an increase in FVC of 22 mL (P = .004). Meanwhile, for every 1 μmg/day increase in vitamin B12 intake, there was an increase of 2.2 mL (P = .006) in FEV1 and 3.8 mL (P < .001) in FVC. In addition, no association was found between vitamin B6 and B12 intake and the FEV1/FVC ratio. There was no gender difference in the effect of vitamin B6 and B12 intake on lung function, and there was a significant trend toward improvement in all relevant indicators with increasing intake. Weighted logistic regression analysis showed that no association was found between vitamin B6 and B12 intake and the risk of airway obstruction. In this regard, we think that higher intake levels of vitamins B6 and B12 may be associated with better lung health.
