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

objectivePrior studies on the association of physical activity (PA) and nonalcoholic fatty liver disease are limited by reliance on subjective measures of PA. We examined the association between objectively measured PA and hepatic steatosis defined by computed tomography (CT).

methodsWe conducted a cross-sectional study of 1,060 Framingham Heart Study participants who participated in the Multidetector CT 2 substudy and who underwent assessment of PA via accelerometry. Hepatic steatosis was estimated by liver attenuation, as measured by CT. We explored the relationship between liver attenuation and PA using multivariable regression models.

resultsIn multivariable-adjusted models, we observed an inverse association between PA and liver attenuation. Each 30 minutes/day increase in moderate to vigorous PA (MVPA) was associated with a reduced odds of hepatic steatosis (OR = 0.62, P < 0.001). This association was attenuated and no longer statistically significant after adjustment for body mass index (BMI) (OR = 0.77, P = 0.05) or visceral adipose tissue (VAT) (OR = 0.83, P = 0.18). Participants who met the national PA recommendations of engaging in ≥150 minutes/week of MVPA had the lowest odds of hepatic steatosis, even after adjusting for BMI (OR = 0.63, P = 0.007) or VAT (OR = 0.67, P = 0.03).

conclusionsThere is an inverse association between PA and hepatic steatosis. Participants who met the national PA guidelines had the lowest prevalence of hepatic steatosis.
