A good quality double-blind randomized controlled study, but :
- Preliminary results with few details in the study methodology regarding the criteria for inclusion of patients or the calculation of the number of subjects needed e.g.
- Change in the main judgment criterion under investigation without explanation of the incidence in terms of statistical power
- No information on the conduct of an Intent to Treat analysis
- No information on the characteristics of the patients actually analyzed in this preliminary study (analysis of all inclusions)
