This completes a result of Dafnis, Giannopoulos and Tsolomitis. We also prove some results in connection with the 1-dimensional marginals of the uniform probability measure on an isotropic convex body, extending the interval in which the average of the distribution functions of those marginals behaves in a sub- or supergaussian way.2015http://zaguan.unizar.es/record/5793610.1090/S0002-9939-2014-12401-4http://zaguan.unizar.es/record/57936oai:zaguan.unizar.es:57936PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY 143 (2015), 821-832byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
