Schematic representation of the potential advantages of using trends. (A) If imprecision or noise is random or normally distributed, the trend line will filter it out. (B) If the measurement system has a fixed bias, trend will not be affected but individual values could be. (C) When trying to predict future events, trend may be clinically more important than the current absolute blood glucose value.
