Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In schools where all students attend in person daily, temporary closures in response to known cases reduce infection spread far less than starting with a hybrid strategy, and they increase disruption to school schedules. → Brian P. Gill 2020

q2 · i? · theoretical · r?
Model comparison of reactive temporary closures versus hybrid operation from the start in fully in-person schools, reported in Key Findings. No effect size printed.
"In schools where all students are attending in person daily, temporary closures in response to known cases are far less effective in reducing infection spread than using a hybrid operating strategy from the start, and they increase the disruption to school schedules."
Discussion¶
Related Claims¶
- Elementary schools are predicted to have lower infection rates than secondary schools using the same operating strategies — related
- Hybrid approaches with smaller masked groups attending part-time dramatically reduce total likely infections, and most outside infections produce zero additional in-school infections — related
- Requiring masks measurably reduces infection spread in schools, according to simulation models of school operating strategies — related
- In Pennsylvania districts using hybrid instruction with precautions in fall 2020, increases in student and staff infections were no greater than community increases outside school — related
- No school is totally low-risk from weather-related disruptions — related
- Reducing student density in classrooms and shared school spaces, combined with precautions such as physical distancing, some mask wearing, and good ventilation, allows for a safer school reopening during COVID-19 — related
