Place the clinical milestones of tetanus in chronological order, from earliest to latest, reflecting the intervals used to assess prognosis (incubation period and period of onset).

The short-IP measure runs from inoculation to the development of trismus. A shorter interval—under seven days—is associated with a worse prognosis in the material. **Key takeaway:** The short-IP clock begins at inoculation and ends at trismus.\n\n**Glossary:** **Incubation period**: time between inoculation and onset of symptoms.
