Additional file 8 of To what extent do mesophotic coral ecosystems and shallow reefs share species of conservation interest? A systematic review LaverickJack PiangoShanice Andradi-BrownDominic ExtonDan BongaertsPim BridgeTom LesserMichael PyleRichard SlatteryMarc WagnerDaniel RogersAlex 2020 Additional file 8. Factor level effects. Predictions of community overlap between shallow and mesophotic reefs by taxon and location, as visualised in Fig. 4. Values are reported as per computer output and in descending order of estimate. The number of studies for each factor level contributing to the model is provided. Reference level indicates which factor level was held constant as the factor of interest was changed. The use of different reference levels should not affect the analysis in the absence of an interaction term in the model.
