Data Comparison

The Data Comparison tool allows users to compare ambulatory activity data collected during private studies with other

public activity datasets that were generated from ActiGraph devices. ActiLife version 5.5.0 introduces this feature with

the option to compare data against one public dataset – the 2003-2004 and 2005-2006 National Health And Nutrition

Examination Survey (NHANES) data collected by the Center for Disease Control and Prevention. More information about

this dataset can be found at

http://www.cdc.gov/nchs/nhanes/about_nhanes.htm.

The goal of the data comparison tool is to provide ActiLife users with the ability to objectively compare their own

actigraphy data with that of national or world-wide standards in an effort to understand correlations among the

datasets. As more datasets become available, ActiLife will continue to expand this offering, eventually providing various

disease research study information and chronic illness baseline data.

The Data Comparison output graphically compares the users’ data to the NHANES data through a series of column

charts.

Loading Datasets for Comparison

Adding Subjects

As datasets are added to the Wear Time Validation and Data Scoring tools, they are automatically loaded into the Data

Comparison tool. To see these datasets (or to load more), click the “Load/Edit Subjects…” button at the top of the Data

Comparison grid. A form similar to the one shown in Figure 56 will appear. Rows highlighted in red indicate that more

metadata information is required in order to fully compare this user to the other users in the baselines database(s). In

the example shown in Figure 56, the user shown in red will be compared on all parameters except for weight. For

instance, three females and three males will appear in the gender comparison graph, but only five users will be

compared in the weight category.
