The possible existence of systematic errors due to reddening in Stromgren uvby photometric data on B stars is investigated by means of statistical analysis of published observational data on a sample of stars in 17 young open clusters. The data are compiled in tables and graphs and characterized in detail. A linear dependence of the observed reddening slope E(c1)MK/E(b-y)MK on spectral type is found and tentatively attributed to a reddening dependence in the coefficients used to transform instrumental values to standard values.
