CEFREF tracks average monthly Headache- / Painkiller-Days over the previous 3-calendar months. Data bars only appear at 3-month end (i.e. data collected from July-September, will only appear 1st October). At month end each 3-month period updates.

 

Each bar consists of blocks indicating average monthly 'Mild', 'Moderate' and 'Severe' Headache-Days. Light blue line indicates average monthly Painkiller-Days.

 

Headache-Days and Painkiller-Days for the highlighted 3-month period are displayed in circles below.
