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

backgroundNon-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease worldwide. This study aimed to estimate the prevalence, incidence, and outcome of NAFLD in the large and diverse population of Mainland China.

methodsPubMed, Embase, and the Cochrane Library databases were searched to identify published studies with NAFLD epidemiology data in adult participants (≥ 18 years old) from Mainland China. Random effects models were used to determine pooled estimates.

resultsWe screened 1,328 studies and included 167 eligible studies (participant n = 1,486,635): 149 studies (n = 1,350,819) for prevalence, 18 studies (n = 147,316) for incidence, 7 studies (n = 5446) for evolution of hepatic steatosis, and 2 studies (n = 647) for mortality analysis. The NAFLD prevalence of the overall populations was 29.88%, with higher rates in males, increasing age and increasing gross regional domestic product (GRDP) per capita (all p ≤ 0.010). The prevalence was the highest in North China (36.41%; higher in Uyghur and Hui Chinese 40.86% and 34.36% vs 28.11% in Han Chinese), higher in diabetics (51.83% vs. 30.76% in non-diabetics) and in obese participants (66.21% vs. 11.72% in lean). The NAFLD incidence was 56.7 (95% CI 47.4-66.8) per 1000 person-years, higher in males and with higher GRDP per capita. The overall mortality was 7.3 (3.3-12.7) per 1000 person-years.

conclusionsThe overall prevalence of NAFLD in Mainland China is about 30%. The highest prevalences were found among regions with higher income, North China, the non-Han ethnic minorities, diabetics, and the obese. China's NAFLD prevalence is on par with Western countries.
