Another thing is to realize that the study compares different sites of infection and different bacterias. So, if I begin with polimyxin and just after 3 days add amikacin, this guy who recive amikacin is the same that our 5th day drunk guy.

The only group which received polymyxin at adequate dose was the VCT group. The median of adequate treatment for monotherapy group was ZERO!

Nothing but the whole truth. Is that honest to compare this group with others? Data and results Patients in the validated polymyxin combination therapy had more severe infections and more serious disease, monotherapy group was older.

Therefore, beer drinkers have lower mortality than sober patients. Combination therapy for non-believers, and believers too!

Therefore, if you read an article showing a possible association between combined therapy and lower mortality and take this as true I can recommend you two books Statistics for Dummies, by Deborah Rumsey and if you can read in portuguese: In their majority, the most cited, are observational trials.

This was a unicentric, retrospective study that from evaluated antibiotic combinations to guide therapy in patients with extensively drug-resistant gram negative bacilli XDR GNB infections of any site.

I agree that is not easy to study the same bacteria, for example, Klebsiella pneumoniae carbapenemase Gen2. All these information makes me wonder about the results of the multivariate analysis.

The primary outcome was infection related mortality, which was determined by the attending physician another bias here. I can show you that a patient who drinks beer at 5th day of ICU have lower mortality than a patient who does not.

Moving on… The eligible patients were divided in three groups: S Army — Delta associates — Memegenerator. The antibiotic dose was included in the multivariate model. Why I hate tramadol but sometimes use it. And also other strange things happened. Bioestatixtica after a multivariate analysis the authors throw the results saying the risk of infection related mortality is 8x greater in MT group and 6x greater in NVCT group when compared to VCT group.
