| Abstract | The purpose of this investigation was to evaluate the association of enteroaggregative Escherichia coli (EAEC) with acute diarrhea in children of South Asian populations. Our meta-analysis included 18 studies published between 1989 and 2011. The odds ratio (OR) was used to evaluate all available observational epidemiology studies. Modifying effects on the overall OR were approached with outlier, subgroup, cumulative, and cumulative recursive analyses. Synthesis of the 18 observational studies revealed an association between EAEC carriage and acute diarrhea, with an overall OR of 1.51, which was significant (p = 0.008), heterogeneous (Pheterogeneity < 0.0001), and unaffected by outlier analysis. This analysis, however, affected the subgroups by eliminating the following: (i) heterogeneity (from Pheterogeneity < 0.0001 to 0.30–0.72) of pooled ORs in the underpowered (OR 1.37, p = 0.15), Indian (OR 1.92, p = 0.09), and hospital-based (OR 1.66, p = 0.06) studies; (ii) non-significance of these three subgroups (OR 1.56–2.01, p < 0.0001–0.003); (iii) significance of the high-powered studies (from OR 1.70, p = 0.02 to OR 1.15, p = 0.28); (iv) heterogeneity (from Pheterogeneity < 0.0001–0.0002 to 0.11–0.15) of pooled ORs in period three (OR 1.85, p = 0.14), population-based (OR 1.36, p = 0.09), and pCVD432 (OR 1.53, p = 0.07) studies. In general, outlier treatment increased precision with the narrowing of confidence intervals, overall, and in the subgroups. Cumulative meta-analysis generally resulted in increases in the frequencies of significant effects and of heterogeneity. This meta-analysis on observational studies suggests that the association between EAEC and acute diarrhea in children is that of increased risk. This effect generally comes from heterogeneous studies of South Asian populations, but is modified with outlier and subgroup treatments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
