However, the smaller Advanced Wound Management business saw flat revenues at $337m despite the global market growing 2%.For the half year as a whole, underlying trading profit was flat at $484m on revenues that improved 2% to $2.22bn."With half of our revenues now coming from higher growth markets, and a more focused structure, we are well placed to take advantage of the many further opportunities we see," said chief executive Olivier Bohuon.The interim dividend was lifted to 11 cents per share, from 10.4 cents the year before.BC
