The Effect of Improved Rural Sanitation on Diarrhoea and Helminth Infection: Design of a Cluster Randomized Trial in Orissa, India

This paper by Clasen et al. (2012), published in Emerging Themes in Epidemiology describes the design of a village-level cluster-randomised trial in the state of Orissa, India to evaluate the impact of an ongoing rural sanitation campaign conducted under the umbrella of India’s TSC. It discusses methodological problems encountered thus far in the study that may be typical for sanitation trials, but concludes that it is expected that the trial procedures will still allow for the effectiveness of a typical rural sanitation campaign to be measured with sufficient accuracy and validity.
