Table 2.
Evidence strength | Effect estimates | Temporal cluster |
---|---|---|
Strong | Selected and significant with intended effect signs (i.e. negative) regardless of model specifications (i.e. variable selection criteria, temporal lags, and time-series lengths). | Not in a temporal cluster with any NPI with significantly positive effect estimates. |
Moderate | Selected and significant with intended effect sign (i.e. negative) in two of three model specification dimensions (i.e. variable selection criteria, temporal lags, and time-series lengths), and non-selected or non-significant in the remaining dimension.* | |
Weak | Not strong or moderate |
*For the moderate category, all the model specifications that were non-significant or non-selected were examined to see if they had a value in common across one of the three criteria, e.g. all of them had a lag of 10 days. Significance was assessed using ⍺ = 0.05
