Figure 1From: Triangular test applied to the clinical trial of azithromycin against relapses in Plasmodium vivax infectionsDesign of the triangular test (upper boundary, Z = 2.58 – 1.51 V; lower boundary Z = -2.58 – 0.50 V) and the results of the three sequential analyses. The Z and V statistics were calculated each time a patient relapsed. The corresponding points were plotted on the graph and compared with the stopping boundaries. On the third analysis, the upper boundary was crossed, causing the inclusion to be stopped.Back to article page
