Crude monthly percentages of mental health consultations and dispensed drugs among students. All outcomes were measured and calculated separately for the pandemic students (solid lines) and pre-pandemic students (dashed lines). The monthly percentages refer to students with at least one mental health consultation or dispensed prescription drug the given month. The x-axis refers to the calendar month where measurements were made for the pandemic students. The pre-pandemic students were measured 12 and 24 months earlier. The timeline of infection control measures, categorized by three levels of stringency, is illustrated on the x-axis (analogous to Fig. 1)
