Site coordinators are trained in standardized data collection techniques and data entry.
Data entry, cleaning, aggregation and analysis techniques involved Statistical Package for Social Sciences SPSSS version 17.0; Chicago, IL, USA) and SAS SASS V9.2; SAS Institute Inc., Cary, NC, USA) statistical software.

We recognize that regular expressions are only appropriate for highly structured, machine-produced data and span the gap between structured data entry and natural language processing techniques for semantically interpreting text such as clinical notes.
Now some companies are looking at an innovative way to combine the rising popularity of camera phones with existing bar code scanning techniques to make data entry less cumbersome and open up the possibilities for mobile commerce applications.
The OpenSDE [ 2] system developed by Renske K. Los et al used row-modelling technique to allow generic structured data entry.
Double entry technique was used to create a gold-standard for data quality.
Murphy et al. [ 11] described the implementation of an EMR and data extraction techniques to facilitate real time and on-site data entry for clinical research.
A common output of these techniques is a trained categorical classifier which receives a new data entry as the input, and outputs a hypothesis for the data points abnormality.
In this paper, we studied a new technique: Online Sequential Extreme Learning Machine (OS-ELM) which is capable of updating the model equation based on new data entry without much increase in computational cost.
