Painkillers and kidney damage

I wonder how many people read far enough into a story like this to realise that unless they are taking painkillers every day AND they are susceptible to kidney problems, that aspirin, paracetamol etc are harmless - at least, as regards our kidneys.

Not that the study is overwhelmingly powerful, anyway. 'Over 200 patients treated for kidney failure across the US were scanned for SICK and asked about their use of painkillers. Seven per cent were found to have SICK, and a third of those patients had overused analgesics,' according to BBC News. In other words, four or five patients with SICK were heavy users.
