Studies that generate real-world evidence on the effects of medical products through analysis digital data collected in clinical practice provide key insights for regulators, payers, and other healthcare decision-makers. Ensuring reproducibility such findings is fundamental to effective evidence-based decision-making. We reproduce results 150 studies published peer-reviewed journals using same databases as original investigators evaluate completeness reporting 250. Original reproduction...

To evaluate the risk of fracture in patients receiving intermittent therapy with high-dose oral glucocorticoids (GCs).The study group comprised 191,752 from UK General Practice Database who were 40 years age and older received GCs. The followup time period was divided into categories "current" "no exposure." daily dose cumulative for each determined. Relative risks estimated using Cox proportional hazards models, adjusted age, sex, body mass index, smoking, disease history, drug history....

Microscopic colitis (MC) is a chronic bowel disorder characterised by watery diarrhoea. Nonsteroidal anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPIs), selective serotonin reuptake (SSRIs) and statins have been associated with MC. However, underlying mechanisms remain unclear.To study the association between exposure to these MC, attention time of exposure, duration, dosage combined test hypotheses on pharmacological mechanisms.A case-control was conducted using British...

OBJECTIVE To assess the risk of colorectal cancer associated with type 2 diabetes, as compared a nondiabetic reference population, and to study additional associations between treatment stage duration obesity risk. RESEARCH DESIGN AND METHODS We conducted an observational population-based cohort within Clinical Practice Research Datalink (1987–2012). All patients (≥18 years) at least one prescription for antidiabetic drug (n = 300,039) were matched (1:1) by birth year, sex, practice...

Stroke increases the risk of hip/femur fracture, as seen in several studies, although time course this increased remains unclear. Therefore, our purpose is to evaluate and investigate any elevated risk.We conducted a case-control study using Dutch PHARMO Record Linkage System database. Cases (n=6763) were patients with first fracture; controls matched by age, sex, region. Odds ratio (OR) for fracture was derived conditional logistic regression analysis, adjusted disease drug history.An...

Methods All incident AS (n=4101) from UK Clinical Practice Research Datalink (1987–2012) were matched up to seven control subjects without by year birth, sex practice (n=28 591). Incidence rates, cumulative rates adjusted (adj) HRs for...

Studies on drug utilization usually do not allow direct cross-national comparisons because of differences in the respective applied methods. This study aimed to compare time trends BZDs prescribing by applying a common protocol and analyses plan seven European electronic healthcare databases.Crude standardized prevalence rates from 2001-2009 were calculated databases Spain, United Kingdon (UK), The Netherlands, Germany Denmark. Prevalence was stratified age, sex, BZD type [(using ATC codes),...

Abstract Patients with multiple sclerosis (MS) may be at an increased risk of fracture owing to a greater falling and decreased bone mineral density when compared the general population. This study was designed estimate relative absolute in patients MS. We conducted population-based cohort using data from UK General Practice Research Database linked National Hospital Registry (1997–2008). Incident MS (n = 5565) were matched 1:6 by year birth, sex, practice without (controls). Cox...

Previous studies evaluated the association between proton pump inhibitor (PPI) use and subsequent fracture risk, but they showed ambiguous results. Therefore, objective was to evaluate this in a different study population. Our findings show that there is probably no causal relationship PPI hip risk. To further test these conflicting results, of PPIs risk hip/femur A case-control conducted using data from Dutch PHARMO record linkage system. The population included 6,763 cases aged 18 years...
