Publication characteristics, including publication year, number of authors, single vs multicenter study, geographic origin of the study, statistician involvement, study category, subject category, types of reliability assessment, and statistical methods applied to assess reliability, were recorded.

Sustained low efficiency dialysis is non-inferior to continuous renal replacement therapy in critically ill patients with acute kidney injury: A comparative meta-analysis.

Background: Critically ill adults with acute kidney injury (AKI) experience considerable morbidity and mortality. This systematic review aimed to compare the effectiveness of continuous renal replacement therapy (CCRT) versus sustained low efficiency dialysis (SLED) for individuals with AKI.

Methods: We carried out a systematic search of existing databases according to standard methods and random effects models were used to generate the overall estimate.

Angiotensin converting enzyme inhibitors and risk of lung cancer: A systematic review and meta-analysis.

Background: We performed a meta-analysis to determine whether a consistent relationship exists between the use of angiotensin converting enzyme inhibitors (ACEIs) and the risk of lung cancer. Accordingly, we summarized and reviewed previously published quantitative studies.

Methods: Eligible studies with reference lists published before June 1st, 2019 were obtained from searching several databases.

Referral Time of Advance Cancer Patients to Palliative Care Services and Its Predictors in Specialized Cancer Center.

Background and aim Globally, there is a discrepancy in whether terminal cancer patients are early referred to palliative care service (PCS) or not. A late referral can lead to a delay in treating and palliating those patients in need. The aim of this study is to investigate the referral time patterns of advanced cancer patients to PCS in Princess Noorah Oncology Center (PNOC) at King Abdulaziz Medical City, Ministry of National Guard Health Affairs, Jeddah, Saudi Arabia.

Efficacy of treatment methods for uncontrolled hypertension and its effects on atrial fibrillation: A systematic narrative review.

Objectives: Uncontrolled hypertension is a main predisposing risk factor leading to chronic atrial fibrillation (AF). Although several treatment methods for patients with HTN and AF were developed in past decades, further investigations of their efficacies are needed. This systematic narrative review presents an overview of studies reporting treatment efficacies in patients with HTN and/or AF.

Effect of donor hypertension on renal transplant recipients' blood pressure, allograft outcomes and survival: a systematic review and meta-analysis.

Background: The effect of donor hypertension on the blood pressure of renal transplant recipients and the allograft outcomes are unclear. The aim of this study was to summarize the evidence about the effects of donor hypertension on renal transplant recipients' blood pressure, renal allograft outcomes and mortality.

Methods: Studies published from January 1960 to 31 January 2019 in English were identified through a systematic search of six databases; PubMed, Embase, SCOPUS, Web of Science, Cochrane Database of Systematic Reviews, and CINAHL.

This study aims to assess the methodological difficulties encountered by healthcare practitioners in conducting clinical research in Saudi Arabia.

Serosurvey of measles, mumps and rubella antibodies in Saudi children.

Objective: A serosurvey study to evaluate the proportion of children with antibodies against diseases targeted by the Expanded Program of Immunization in the Kingdom of Saudi Arabia.

Methods: Using multistage sampling techniques, we collected samples and sent them for laboratory assay from the following age groups; 100 samples at 6 months, 12 months, 18 months, 6 years, 13 years, and 17 years. We conducted the study from September 2001 to February 2002.

Screening of pregnant Saudi women for hepatitis B surface antigen.

Background: The high prevalence of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) in pregnant women is considered the most important factor contributing to the higher carrier rate of HBsAg in some populations, including Saudi Arabia. Universal hepatitis B vaccination in infancy was implemented in Saudi Arabia in 1990 to avoid early acquisition of infection. At the same time, another program was launched to vaccinate all school children at school entry as a second target group.
