1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study sought to determine if dietary macronutrient consumption and the low-carbohydrate diet (LCD) score were linked to rheumatoid arthritis (RA).

methodsParticipants ≥ 20 years were analyzed from the National Health and Nutrition Examination Survey (NHANES) 2011-2016. LCD score was calculated by summing the 11 quantiles values of the percentages of energy derived from carbohydrate, protein, and fat. Weighted logistic regression, eXtreme Gradient Boosting (XGBoost), and Light Gradient Boosting Machine (LightGBM) models were used to explore the relationship between LCD score, dietary macronutrient intake, and RA. Propensity score matching (PSM) were applied for sensitivity analysis.

resultsUltimately, 8118 participants (RA: 499, without RA: 7619) were analyzed. After fully adjusting for confounders, a negative association was found between the LCD score and the presence of RA [OR (95% CI), 0.97 (0.96, 0.99)]. A higher LCD score was also negatively associated with a lower likelihood of RA based on a categorical model. Among macronutrients, participants in the third and fourth quartiles had significantly increased odds of RA compared with the lowest carbohydrate intake. Regarding protein intake, individuals in the highest quartile of percentage of energy from protein had a 46% lower presence of RA compared with the lowest reference group. The relative importance of the LCD score on RA was determined based on XGBoost and LightGBM models. Moreover, the association between the LCD score, dietary macronutrient intake, and RA presence remained substantial after PSM.

conclusionsLCD score was negatively associated with odds of RA in US adults. Moreover, a correlation was found between a lower likelihood of RA and high protein, and low carbohydrate consumption. Key Points • A significant negative association was found between LCD score and RA presence. • Machine learning models revealed the LCD score was a significant predictor of the presence of RA. • Low carbohydrate intake and high protein intake were correlated with a lower odds of RA.
