Rates were flat in a sense of temporal continuity - they stayed around a level that is normal some of the time.

They were very far down in a sense of seasonality. Teen suicide rates are -- normally -- much higher during the school year than they are during the summer.

> The first school year of the pandemic (with full lockdowns) also represents the FIRST TIME IN 21 YEARS that March-June (school months) had the same low suicide rate as July (non school month). Typically, school months associated with 36-55% increase [in suicide] in HS kids.

So about a 30% decrease in suicide rate from shutting down school. I would argue that a 30% decrease qualifies as "dramatic".
