Δχ2 (DF), p-value -- Δχ2 (28) = 131.73*** Δχ2 (27) = 47.93, 0.0003

Note. Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), the standardized root mean square residual (SRMR), and the root-mean-square error of approximation (RMSEA). Δχ2 represents the difference test between the current model and the model run previously (i.e., to the left of the current column).
