Extended Data Fig. 1: Estimated daily distributed lag parameters describing the association between viral RNA in sludge and positive COVID-19 tests, based on date of report to CT Department of Health.
From: Measurement of SARS-CoV-2 RNA in wastewater tracks community infection dynamics
The top row figures are adjusted for testing volume, bottom row figures are unadjusted for testing volume. a, daily lags of sludge data at longer time lags (0 to 4 days in the past) best correlate with the time series of reported positive tests (adjusted). b, cumulative relationship between viral RNA in sludge and number of positive tests (adjusted). c, daily lags of sludge data at longer time lags (0 to 4 days in the past) best correlate with the time series of reported cases (not adjusted for number of tests). d, cumulative relationship between viral RNA in sludge and number of positive tests (not adjusted). The posterior means at the center of each data point and 90% credible intervals for error bars are displayed. For each lag, n=73 daily virus RNA samples, n=75 daily reported adjusted positive test values, n=75 daily reported unadjusted positive test values.
