  1. The highest prevalence in each category is in bold italics for emphasis
  2. Statistical outputs were derived from minimum sufficient models, after first fitting for each species in turn, all variables into a single full factorial model, and then stepwise backward deletion of non-significant terms. The χ 2 values for goodness of fit of the minimum sufficient models for hookworms, T. trichiura, A. lumbricoides, H. nana and all helminths combined was as follows: 792.2 (df = 1854, P = 1), 717.9 (df =1813, P = 1), 720.4 (df = 1814, P = 1), 759.6 (df = 1814, P = 1) and 978.7 (df = 1846, P = 1), respectively. The importance of each factor in the final minimum sufficient model for each taxon is given in the text
