Systematic Review and Meta-Analysis to Estimate the Burden of Non-Fatal and Fatal Overdose Among People Who Inject Drugs Living in the United States and Comparator Countries: 2010 – 2023
BACKGROUND: People who inject drugs (PWID) have high risk for overdose, but there are no current estimates of overdose rates in this population. We aimed to estimate rates of non-fatal and fatal overdose among PWID living in the United States (US) and comparator countries (Canada, Mexico, United Kingdom, Australia), and ratios of non-fatal to fatal overdose rates, using literature published 01/01/2010 - 09/29/2023. METHODS: PubMed, PsycINFO, Emba…
Analyzing the Discursive Framing of Medications for Opioid Use Disorder (Mouds) in U.S. News Media: A Comparative Study of Benefits, Persuasion Methods, and Temporal Trends
Medications for opioid use disorder (MOUDs) offer substantial benefits but are underutilized. Media representations of MOUD benefits potentially shape public and policymaker attitudes toward these treatments. This study examines how MOUD benefits are portrayed in the news media, exploring variations by medication type, publication period, news source, and persuasion approach. We analyzed 81 articles from the New York Times, USA Today, and Fox New…
Exploring the Methodological Quality of Education Intervention Meta-Analyses: A Meta-Review
This meta-review explored the current practices used in education intervention meta-analyses in terms of systematic review procedures and meta-analysis methods. We reviewed 247 meta-analyses on the effects of K–12 school-based interventions on student academic achievement published after 2011. We found that many reviews were mostly consistent with several best practice recommendations for the review stage, including problem formulation, selection…

A Meta-Analysis of Mathematics Word-Problem Solving Interventions for Elementary Students Who Evidence Mathematics Difficulties
Since 1975, researchers have conducted interventions to improve the word-problem performance of elementary school students facing mathematics difficulties. The current study reports a meta-analysis of 52 studies that examined the effect of these interventions. We estimated multivariate, random-effects models (REM) with robust variance estimation (RVE) with and without outliers. Results showed a large, positive, and significant mean weighted effec…
Promoting Knowledge Accumulation About Intervention Effects: Exploring Strategies for Standardizing Statistical Approaches and Effect Size Reporting
Toward the goal of more rapid knowledge accumulation via better meta-analyses, this article explores statistical approaches intended to increase the precision and comparability of effect sizes from education research. The featured estimate of the proposed approach is a standardized mean difference effect size whose numerator is a mean difference that has been adjusted for baseline differences in the outcome measure, at a minimum, and whose denomi…
Quality of Research Evidence in Education: How Do We Know
The persistence of inequitable education is the fundamental fact facing education researchers as we reflect on the quality and value of the evidence we produce (American Educational Research Association & National Academy of Education, 2020; Educational Opportunity Monitoring Project, 2020). As a field, we must critically examine what it means for us to develop increasingly sophisticated research tools and research design models while disparate o…

Outcome-Reporting Bias in Education Research
Outcome-reporting bias occurs when primary studies do not include information about all outcomes measured in a study. When studies omit findings on important measures, efforts to synthesize the research using systematic review techniques will be biased and interpretations of individual studies will be incomplete. Outcome-reporting bias has been well documented in medicine and has been shown to lead to inaccurate assessments of the effects of medi…
