SiDiary for Android - Manual - Trend

(Please click here to download the manual in PDF format)


Android App The trend analysis compares two time ranges to analyze the progression. Parameters are: Frequency (of bg level tracking), calculated A1C, standard deviation and postprandial levels (bg level after meals).

If you select '1 Week' in the settings for the analysis, then the last 7 days will be compared with the previous 7 days.
'Trend' shows you (with arrow symbols) if this parameter has become worse, is constant or has become better than in the previous time range.

'Level' shows you the current situation with a smiley symbol (in '1 Week' it shows the level of the last 7 days).

The set of criteria for the level:

... Excellent Good Satisfactory
Frequency: More than 3 equal to 3 less than 3
Calculated A1C: less than 6,5% less than 7,5% less than 9%
Standard deviation: less than 60 mg/dl (3,3 mmol/l) less than 70 mg/dl (3,9 mmol/l) less than 80 mg/dl (4,4 mmol/l)
Postprandial level: less than 60 mg/dl (3,3 mmol/l) less than 80 mg/dl (4,4 mmol/l) less than 100 mg/dl (5,5 mmol/l)

A blood glucose value will be calculated as 'postprandial' if the measurement comes 60-120 minutes after an entry for carbohydrates.

In the settings for 'Trends' (via the i-symbol at the top) you can select which time ranges should be calculated and which parts of a day you want to analyze for the postprandial levels.

The parts of day are:

  • After breakfast: 10:00 - 11:59 (10:00am - 11:59am)
  • After lunch: 15:00 - 16:59 (03:00pm - 04:59pm)
  • After dinner: 20:00 - 03:59 (08:00pm - 03:59am)
