In the Journal of Asthma 2013, 50: 296–301, for the article “Effects of Omalizumab in Non-Atopic Asthma: Results from a Spanish Multicenter Registry,” errors have been noticed since publication.
In the abstract, the results section incorrectly stated the GETE measurements increased to 2.8 ± 0.8 but should have read 2.8 ± 0.9. Also, it stated that the ACT measurements increased from 13.0 ± 5.5 when it should have read 13.3 ± 5.5. The corrected section should have read as follows:
Results. Omalizumab demonstrated significant improvement in the clinical status of non-atopic asthmatics as measured by GETE, which rose from 1.6 ± 1.1 to 2.8 ± 0.9 at 4 months (p = .0215), to 2.9 ± 0.9 at 1 year (p = .0093), and to 3.4 ± 0.6 at 2 years (p = .0078), and by the ACT, which increased from 13.3 ± 5.5 to 17.5 ± 5.4 at 4 months (p = .0236), to 17.9 ± 4.8 at 1 year (p = .0136), and to 20.6 ± 3.9 at 2 years (p = .0024). Forced expiratory volume in 1 second (FEV1) improved from 61.0 ± 19.4% to 65.1 ± 17.2% at 4 months, to 64.1 ± 24.7% at 1 year, and to 67.3 ± 23.0% at 2 years, but without significant differences between initial and follow-up measurements (p = .52, .91, and .45, respectively), and exacerbations decreased from 3.1 ± 3.5 to 1.9 ± 2.8 at 1 year (p = .1709) and to 1.8 ± 4.4 at 2 years (p = .2344). The results were not significantly different from those obtained in atopic asthmatics.
In addition, Figure 1b incorrectly showed the baseline ACT as 13.0 when this should have instead read 13.3. The figure should have appeared as shown below:

Finally, in the Results section of the paper, the p value is incorrectly shown in the sentence beginning “The performance evaluated by the GETE increased . . .”, it read p = .078 but should have read p = .0078 as shown below:
“The performance evaluated by the GETE increased from 1.6 ± 1.1 to 2.8 ± 0.9 at 4 months (p = .0215) to 2.9 ± 0.9 at 1 year (p < .0093) and 3.4 ± 0.6 at 2 years (p = .078) in (here the correction is: p = .0078) the non-atopic group. Furthermore, the ACT increased from 13.3 ± 5.5 to 17.5 ± 5.4 at 4 months (p < .0236) to . . .”.
