Correction: Longitudinal co-variations between inflammatory cytokines, lung function and patient reported outcomes in patients with asthma.

[This corrects the article DOI: 10.1371/journal.pone.0185019.].

In Tables 4 and 5, the direction of all correlations involving the variable sickness are reversed (i.e. positive correlations were labelled negative with a minus sign and vice versa). The correlations are described correctly in Results and the conclusion of the paper is not affected. Please see the corrected Tables 4 and 5 here.

Table 4

Spearman’s correlations for changes in cytokines, FEV1, sickness behaviour, asthma-related quality of life and self-rated health between baseline and follow-up in women.

Women	IL-5	IL-6	FEV1	Sickness	SRH	mAQLQ
IL-5	1.00
IL-6	-0.06	1.00
FEV11	-0.07	0.02	1.00
Sickness2	-0.05	-0.07	0.06	1.00
SRH3	-0.18	-0.04	-0.09	0.21*	1.00

***p<0.001

1 Percent predicted

2Composite variable of rating of energy, sleep, memory, fitness and appetite where higher scores denotes more pronounced sickness behaviour

3Higher scores on self-rated health denote worse self-rated health

4Higher scores denotes better asthma-related quality of life
