Erratum to: Pneumococcal lower respiratory tract infections in adults: an observational case–control study in primary care in Belgium

The original article was published in BMC Family Practice 2015 16:66

Due to a change in reagent affecting the performance of the Urinary Antigen Detection (UAD) assay, the positivity cut-off values of the assay had to be revised. A number of epidemiological studies have been affected by this change, including the original version of this article [1].

All samples of the study have been reanalysed and the impact on the study results can be found in the attached Excel sheet (Additional file 1):

  • Due to change in cut-off for serotype 5 and 14, there is one case of serotype 5 and of serotype 14 less.

  • The revision of the analysis showed 1 additional positive results for serotype 18C and for serotype 23 F

  • Overall the total number of positive UAD results has not changed.

Results of the assay are shown in the corrected Tables 3 and 4, included in this erratum.
