A corrigendum on
Ten year neurocognitive trajectories in first-episode psychosis
by Barder, H. E., Sundet, K., Rund, B., Evensen, J., Haahr, U., Hegelstad, W., et al. (2013). Front. Hum. Neurosci. 7:643. doi: 10.3389/fnhum.2013.00643
A small part of the data on five of the 43 patients was accidentally displaced in the data file, which affected two of the results presented in the original manuscript.
The statistical significance of the MANCOVA (controlling for IQ and education) is not statistically significant. However, the effect size is still substantial (η2 = 0.444). The Motor Speed index does not show a statistically significant interaction with relapse-group, leaving Figure 4 redundant. A few minor changes in the decimals are added to Tables 1, 3.
Table 1. The four neurocognitive indices with the corresponding subtests and raw scores at each time point for the follow-up sample (Corrected numbers in red).
Table 3. Results from MANOVA; effects of early relapse on neurocognitive indices over time (Corrected numbers in red).
