Introduction:
Liver diseases are of three types which can occur due to the consumption of alcohol such as fatty liver, alcoholic hepatitis, and cirrhosis. But fatty liver has become please check grammar common nowadays and its cases are increasing day by day in the united states. (white, 2012). (please check grammar)
But unlike other liver diseases, it is reversible and it can be treated by quitting alcohol consumption. Fatty liver has become quite common among persons who frequently consume alcohol because liver and git are the main sites in our body where alcohol is metabolized. There are two pathways of alcohol metabolism in our body: alcohol dehydrogenase, cytochrome p450 (moriya, 2015). No effective introduction
Methodology:
Method: i need effective detail on methods

Discussion:
Article 1: cross-sectional study authored by wong et al. 2019 (cross-sectional study authored by alam et al)
In this cross-sectional study, different diseases were considered in the american population such as alcoholic fatty liver disease, alcoholic hepatitis, cirrhosis, complications caused by cirrhosis (wong, 2019). This study was conducted by taking the data of patients between 2001- 2016. The study population was selected after taking proper interviews and medical examinations. The liver enzyme levels, gender, previous medical history, and duration of alcohol consumption were taken into account before conducting this study (wong, 2019)
This study was conducted on the study population after taking interviews and medical examinations on persons. While examining patients, their alcohol consumption habit was taken into account. Hepatitis b and hepatitis c patients were excluded from this study (wong, 2019).
Then statistical analysis was applied to get its results. Multivariable logistic regression was applied to obtain results and linear trends in prevalence were also analyzed. Results showed that there were about 4.3% of persons who were identified with afld. Its prevalence remained stable till 2016 with stage 1. But the prevalence of afld increased by 0.6% during this tenure (wong, 2019).
Article 2: case-control study authored by corrao et al. 1993 ( case control study authored by gupta et al)
This case-control study indicates the prevalence of alcoholic liver diseases. This study was mainly conducted in the hospital so 320 patients were selected after the interview and medical examination (corrao, 1993). Then 320 pairs were matched with these patients to conduct a case-control study. Their lifetime alcohol consumption was also considered with it.
Then the results were obtained by statistical analysis. Conditional logistic regression was applied to obtain results. And it increased from 1 to 4.2 for ldai of 25 g or more. This study was conducted on patients who were consuming alcohol from 10 years to 30 years (biselli, 2010).
The results suggested that there are dose-dependent relationships between liver disease and consumption of alcohol. And it gives rise to various diseases such as alcoholic fatty liver, alcoholic cirrhosis.
Article 3: cohort study authored by setiawan et al. 2016 cohort study authored by jayalekshmi et al
This cohort study aims to analyze the epidemiology of alcoholic liver diseases as liver diseases and cirrhosis have become major sources of mortality and morbidity in the united states. It has been studied that in 2013 more than 36000 deaths occurred due to liver diseases in the united states. The untreated alcoholic fatty liver led to chronic liver disease which caused almost 66,000 deaths in united states in a year. The prevalence of the liver disease has been increased from 1988 to 2008 (setiawan, 2016).
This prospective cohort study was performed on more than 215,000 males and females. This study was conducted on patients of age 45- 75 years old. The cld and cirrhosis were identified on the basis of inpatient and outpatient history. Their alcohol-related disorders were also considered for this study such as alcohol consumption rate, alcoholic neuropathy (stepanova, 2013).
Then statistical analysis was applied to obtain its results. The whole analysis was performed by using the sas system. This study was performed on 5,783 persons, these patients were suffering from chronic liver disease followed by alcoholic fatty liver. Some of these patients were suffering from cirrhosis and some had no cirrhosis (setiawan, 2016). About 51.7% of patients had nafld, 8.6% of patients had ald. The persons who were at the age of 70 years or more were at high risk of developing of chronic liver disease.
Discussion on bias, confounding factors and chances
Bias is a systematic error and it should be minimized by proper selection of cases and proper measurement. Because any error or biases can lead to false results. Research studies also depend on confounding factors sometimes, it arises when risk factors and outcomes both are dependent on or associated with a third variable (white, 2012).
To reduce confounding or to avoid it, those controls should be selected who are independent of exposure. It can also be reduced by randomization and matching. It can also be adjusted by applying different statistical analysis such as multivariable analysis and stratified analysis.
Stratification is the best technique and most of the researchers use this technique. Chance is also an error that can occur during research but it is a sample and it can be minimized by recruiting a large sample (zakhari, 2016).
Conclusion:
This paper concluded that alcohol is associated with many liver diseases such as alcoholic fatty liver, chronic liver disease etc. If it is not treated then it may lead to chronic liver disease or cirrhosis which are untreatable in most of the cases (zakhari, 2016). The widespread of this alcoholic fatty liver diseasea is increasing day by day in the united states and females are at high risk of this liver disease. The development of alcoholic fatty liver is dose-dependent and duration-dependent of alcohol.
