q2 · i? · design · r?

Modeling results on the relationship between strategy effectiveness and lost in-person school days. The report states the most effective strategies "also increase the number of in-person school days lost" and that schools "will need to weigh this tradeoff." No magnitudes are printed.

"However, the most effective strategies for decreasing transmission also increase the number of in-person school days lost, and schools will need to weigh this tradeoff."
