“The power of the pivot”

I have just been analysing 330,000 genital swab results with regards to trichomonas prevalence in different patient cohorts. (such fun!)

Microsoft Excel and its counterparts were fairly rudimentary when I was a trainee 20 years ago. Now the newer versions are extremely powerful tools, very user friendly and with the capacity to produce results within minutes that only a generation ago would have taken research students several months .
