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

backgroundLimited research has been conducted on the effects of dietary fiber (DF) intake on gallstones. We aimed to investigate the actual DF intake in a nationally representative sample in the United States (US) and explore its association with gallstones.

methodsWe used data from the National Health and Nutrition Examination Survey database, including the 2017-2020 and 2021-2023 cycles. Using participants' gallstone histories and their average 2-day DF intake, we investigated the actual DF intake among US adults. After adjusting for traditional confounders, we used weighted multivariable logistic regression models, trend tests, spline curve fitting, subgroup analyses, and interaction tests to explore the independent association between DF intake and gallstones.

resultsA total of 8,782 participants were included. The weighted analysis showed the prevalence of gallstones is 10.03%. The average DF intake among adult men and women is 18 ± 10 g/day and 15 ± 7.8 g/day, respectively, which is well below the recommended levels. Multivariable regression analysis revealed a statistically significant negative linear association between DF intake and gallstone prevalence. For every 10 g/day increase in DF intake, the risk of gallstones significantly decreases by 21% (OR = 0.79, 95% CI: 0.63-1.00, P = 0.047). Curve fitting showed a negative linear relationship between these two variables (P = 0.003, P for non-linearity = 0.134).

conclusionA negative linear relationship between DF intake and gallstones among adults in the US was observed, and the current DF intake in the US is far below recommended levels.
