Dosering to gange dagligt var dog en smule mere effektiv hos patienter, der havde risiko for nedsat virkning af hiv - behandlingen enten på grund af højt virusindhold, lav grad af immunitet eller få behandlingsmuligheder.
However, the twice- daily dose was slightly more effective in patients who were at risk of a reduced response to HIV treatment, due to high viral load, low levels of immunity or few available treatment options.
