  • *Percentage among reported answers (excluding ‘Not reported’).

  • †In some cases more than one clinical indication or diagnostic goal was reported and therefore, the sum of percentages exceeds 100%.

  • ‡Other include: stenocardia (2×), myocarditis (2×), intercostal neuralgia, vertebral blockage, bronchial asthma, transient ischaemic attack, sprained ligaments.

  • §We were not able to follow-up the CRP-POCT test results nor do we know why the physicians did not report these test results.

  • CRP, C-reactive protein ; POCT, point-of-care testing .
