Physiological Parameters Analysis

Step 1: Investigation Stage Selection

The first step of investigation is to select investigation stage. That is because . different stages of investigation target different groups,and the analysis indexes are differentiated. You can refer to the database description for more details.

Step 2: Analysis Type Selection

1. Basic analysis: it relates to the routine analysis of a single index;

2. Comprehensive analysis: At this stage, it relates to a correlation analysis of two indexes; analysis results include correlation charts.

The default option is a basic analysis,namely single index analysis.

Step 3: Analysis Parameter Selection

1. First select the major category of the analysis index

  • 2001 – 2005 analysis indexes included: general physique, blood biochemistry, circulation function, bone density, and respiratory function.
  • 2006 – 2011 analysis indexes included: general physique, body composition, respiration function, circulation function, ECG, blood biochemistry and immunology tests, complete blood count (CBC), and dry-chemistry urine analysis.

2. Then select the more detailed indexes. Index data is divided into two categories:

  • Query results for one type of indexes (such as general physical fitness level) include: the mean value, standard deviation, percentiles, frequency distribution chart, age trend charts (line graph). The age trend chartsgenerally include comparison lines of different genders, different provinces, and different nationalities.
  • Query results for the other types of indexes (such as dry-chemistry urine analysis) include: sample percentages, a configuration diagram of the sample percentage (pie chart), age trend chart (bar graph). Generally, the age trend chart also includes comparison bars of the items mentioned above.

Step 4: Analysis Population Selection

Following the three steps mentioned above, surveyors can analyze the selected indexes of all people at a certain investigation stage. Therefore, this option is done by default in step 4.

Step 4 represents a further screening of the analysis population. The restrictions here include: gender, province, nationality, age, and other survey indexes. The sample size will smaller with screening.

Explanation:

1. When the sample size is<15, there will be a prompt that the selected sample size is too small. Please re-identify the sample size;

2. The age option has no effect on the age trend chart. The age trend chart shows the trend for all ages. The line graph for the age trend chart shows filtered data. This means that if the sample number of a certain age is less than 15, no data of this age will be displayed; if the sample number of every age group is less than 15, no line will appear on the chart.
