| Abstract | Objective: Classification tree analysis is a potentially powerful tool for investigating multilevel interactions. Within the context of colon cancer etiology it may help identify disease pathways and evaluate important interactions of risk factors. Methods: We apply classification tree analysis as a statistical method to investigate interactions of risk factors for colon cancer. We use data collected from a population-based case–control study of newly diagnosed cases of colon cancer (N = 4403 cases and controls). Results: Our results indicate that, as expected, there are many factors that influence colon cancer risk, and that they interact on many levels. We find that the most important factor is the utilization of aspirin and/or non-steroidal anti-inflammatory drugs (NSAID), with those taking this medication having lower risk. Family history appears as a level two modifying factor when NSAID are not used, whereas Western diet is the second factor when NSAID are taken. The final tree has six levels, contains several modifying factors and correctly classifies case or control status for 60.8% (95% CI 59.4–62.2) of all individuals. Conclusions: Our results suggest that risk factors work together to determine disease risk. By accounting for interactions between risk factors we become better able to dissect disease pathways and determine those risk factors that increase susceptibility to disease. Our results highlight the importance of designing studies so that interactions can be addressed. |

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.
