Guidelines for the Content of Statistical Analysis Plans in Clinical Trials

While guidance on statistical principles for clinical trials exists, there is an absence of guidance covering the required content of statistical analysis plans (SAPs) to support transparency and reproducibility. Recommendations are provided for a minimum set of items that should be addressed and included in SAPs for clinical trials. Trial registration, protocols, and statistical analysis plans are critically important in ensuring appropriate reporting of clinical trials.

Development of an online resource for recruitment research in clinical trials to organise and map current literature

by Anna Kearney, Nicola Harman, Anna Rosala-Hallas, Claire Beecher, Jane Blazeby, Peter Bower, Mike Clarke, William Cragg, Sinead Dune, Heidi Gardner, Patricia Healy, Lisa Maguire, Nicola Mills, Leila Rooshenas, Ceri Rowlands, Shaun Treweek, Akke Vellinga, Paula Williamson, Carrol Gamble

Transparency in the conduct and reporting of clinical trials is supported by the guidance produced on the content of clinical trial protocols and reporting standards for clinical trials. While the principle features of the statistical analysis are required within this guidance it is generally accepted that a separate Statistical Analysis Plan is also developed as the level of detail appropriate for a SAP is excessive for a protocol. However, there is no detailed guidance on the content of a SAP and consequently, there is marked variation in practice.

These recommendations are intended as a tool to help research staff and community representatives expand and deepen existing partnerships, and forge new ones, with the ultimate goal of facilitating effective community engagement in all aspects of clinical trials research.

Fetal Growth Standards for ultrasound measurements of head circumference (HC), bi-parietal diameter (BPD), occipito-frontal diameter (OFD), femur length (FL) and abdominal circumference (AC) are now available for download. For information about how to perform these measurements, or for other information on standards in ultrasound imaging, please see the ultrasound training toolkit.

Practical chart for health practitioners to use to assess newborn size (weight, length, head circumference) at birth against global standards. This version of the chart is being piloted within the University of Oxford hospital network, and plans to pilot in the INTERGROWTH-21st study sites and in Boston area hospitals are developing quickly. Practitioners can download and use this version of the chart freely. To connect with the INTERGROWTH-21st team regarding your experience with piloting this chart, or to request modifications to the chart (e.g. language; different institutional logo), please contact intergrowth21st@tghn.org.

New BMJ Open article: “Understanding the investigators: a qualitative study investigating the barriers and enablers to the implementation of local investigator-initiated clinical trials in Ethiopia” This article was written by the research team at Global Health Trials in collaboration with researchers from Ethopia, Sri Lanka and Peru. The research was initiated in response to the low volume of clinical trials conducted by investigators in Low and Middle Income Countries.

The last decade has witnessed a substantial increase of multi-centre, public health-oriented clinical trials in poor countries. However, non-commercial research groups have less staff and financial resources than traditional commercial sponsors, so the trial teams have to be creative to comply with Good Clinical Practices (GCP) requirements. This article hopes to feed the reflection on the methodological and ethical aspects of clinical trials carried out in developing countries by North-South collaborative research groups.

This paper, recently published on the Italian Journal of Tropical Medicine(Vol 15, N 1-4, 2010), reports on a debate that took place during the 6thEuropean Conference of Tropical Medicine in 2009, on some topics of greatinterest for GlobalHealthTrials.org: is there a global standard for clinicalresearch? Should standards be adapted in developing countries? How toencourage research while preventing the exploitation of vulnerableindividuals or groups? Five "debate questions" where addressed by ProfessorNick White and by Dr. Lumuli Mbonile, and discussed with the moderator(Raffaella Ravinetto) and the audience.
