A systematic review and meta-analysis of the evidence on learning during the COVID-19 pandemic.

To what extent has the learning progress of school-aged children slowed down during the COVID-19 pandemic? A growing number of studies address this question, but findings vary depending on context. Here we conduct a pre-registered systematic review, quality appraisal and meta-analysis of 42 studies across 15 countries to assess the magnitude of learning deficits during the pandemic. We find a substantial overall learning deficit (Cohen's d = -0.14, 95% confidence interval -0.17 to -0.10), which arose early in the pandemic and persists over time. Learning deficits are particularly large among children from low socio-economic backgrounds. They are also larger in maths than in reading and in middle-income countries relative to high-income countries. There is a lack of evidence on learning progress during the pandemic in low-income countries. Future research should address this evidence gap and avoid the common risks of bias that we identify.

Addressing epistemic injustice in HIV research: a call for reporting guidelines on meaningful community engagement.

INTRODUCTION: Despite the widely recognized ethical and practical benefits of community engagement in HIV research, epistemic injustice persists within the field. Namely, the knowledge held by communities disproportionately affected by HIV is systematically afforded less credibility than that of more privileged academic researchers. In order to illustrate what this looks like in practice, we synthesized the extent of reporting on community engagement within recent high-impact HIV intervention research papers. However, we also posit that the HIV research sector has the potential to devise and showcase world-leading examples of equitable research-community partnerships and suggest actionable key steps to achieving this goal. DISCUSSION: In the absence of reporting requirements within the publishing process, it is difficult to infer whether and how the community have been consulted in the design, implementation, analysis and/or interpretation of findings. As an illustrative exercise, we offer a rapid synthesis of the extent of reporting on community engagement in HIV research from 2017 to 2019, which highlighted sporadic and very low rates of reporting of community engagement in recent high-impact HIV intervention studies. Of note is that none of the included studies reported on community engagement through all stages of the research process. There were also discrepancies in how community involvement was reported. We provide three actionable recommendations to enhance reporting on community engagement in HIV research: (1) community-led organizations, researchers and scientific journals should band together to develop, publish and require adherence to standardized guidelines for reporting on community involvement in HIV research; (2) research funders should (continue to) require details about how relevant communities have been engaged prior to the submission of funding requests; and (3) researchers should take proactive measures to describe their engagement with community organizations in a clear and transparent manner. CONCLUSIONS: There is a clear and urgent need for guidelines that facilitate transparent and consistent reporting on community engagement in HIV intervention research. Without standardized reporting requirements and accountability mechanisms within the research sector, the extent of meaningful community engagement cannot be established and may remain a catchphrase rather than reality.

A systematic review and meta-analysis of the impact of cash transfers on subjective well-being and mental health in low- and middle-income countries.

Cash transfers (CTs) are increasingly recognized as a scalable intervention to alleviate financial hardship. A large body of evidence evaluates the impact of CTs on subjective well-being (SWB) and mental health (MH) in low- and middle-income countries. We undertook a systematic review, quality appraisal and meta-analysis of 45 studies examining the impact of CTs on self-reported SWB and MH outcomes, covering a sample of 116,999 individuals. After an average follow-up time of two years, we find that CTs have a small but statistically significant positive effect on both SWB (Cohen's d = 0.13, 95% confidence interval (CI) 0.09, 0.18) and MH (d = 0.07, 95% CI 0.05, 0.09) among recipients. CT value, both relative to previous income and in absolute terms, is a strong predictor of the effect size. Based on this review and the large body of existing research demonstrating a positive impact of CTs on other outcomes (for example, health and income), there is evidence to suggest that CTs improve lives. To enable comparisons of the relative efficacy of CTs to improve MH and SWB, future research should meta-analyse the effects of alternative interventions in similar contexts.
