Flow chart of study sample. NB. Since individuals could have both low and high impact symptoms the dotted vertical line represents a split in the flowchart. The left-hand side shows the 1681 individuals divided into those without and with low impact symptoms and whether the latter consulted about them or not. The right-hand side shows the same information about high impact symptoms. Of the 1681 individuals with symptoms, 244 consulted a GP about at least one symptom. Of these, 39 individuals were both a low impact consulter and a high impact non-consulter and 59 individuals were both a low impact consulter and a high impact consulter.
