I'm not sure of the details of the testing procedure (controls, etc.) but thought it worth mentioning that also, after the initial four-week trial (that I presume has already begun) at Government General & Chest Hospital there will be a follow up trial which will last 4 months at Bhaskar Medical College. So whatever the initial results there will be further testing shortly afterwards over a greater duration.
Even if the testing period at GG & C Hospital has just ended we need to allow some time for the analysis and results to be written before expecting an ANN. Having said that I'm as keen as anyone else for the results and expect strong conclusions that will demonstrate that the tech works. I'd expect further tests at Bhaskar will consolidate the initial findings and become a more generalised benchmark for the manufacturers.
