Funnel plots of the Standardized Mean Difference versus the standard error are prone to distortion, leading to false-positive tests for funnel plot asymmetry, and therefore using the Normalised Mean Difference, or a sample size-based precision estimate, are more reliable alternatives.

Meta-analysis takes down a textbook example in behavioural and evolutionary ecology, and demonstrates the existence of biases in the current scientific publishing culture.

A complete public catalogue of brain recording data from a single laboratory has revealed new scientific findings, and has also shed light on aspects of the scientific process, such as statistical power and publication bias.

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder of women, with significant reproductive, endocrine, and metabolic morbidities and a total healthcare-related economic burden exceeding $15 billion (2021 USD) for the U.S. alone, $4 billion due to mental health disorders.

Bidirectional causal relationship between higher sedentary time and higher adiposity suggests that decreasing sedentary time is beneficial for weight management, but also that weight loss may help reduce sedentary time.

A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.

Regional meta-analysis enriches our understanding of zoonotic malaria in primate reservoirs in areas of Southeast Asia experiencing deforestation, with wider ecological implications for human disease risk in fragmented landscapes.

While men’s mating success is predicted both by their strength/muscularity, voice pitch, height, and testosterone levels, their reproductive output is only predicted by strength/muscularity.

The inward-open and outward-open structures of MjNhaP1 explain the mechanism of electroneutral sodium-proton antiport across the cell membrane.

The combination of data and modelling shows the mechanisms underlying bidirectional flow of cerebrospinal fluid and its impact on long range transport in the CSF between brain and spinal cord.
