Example from the Literature – Salicylic Acid Plasters for Treatment of Foot Corns

Оглавление

Table 2.1 gives a typical table reporting baseline characteristics of a set of patients entered into a randomised controlled trial that investigated the effectiveness of salicylic acid plasters compared with usual scalpel debridement for treatment of foot corns (Farndon et al. 2013). Corns and calluses are areas of hard, thickened skin that develop when the skin is exposed to excessive pressure or friction. They commonly occur on the feet and can cause pain and discomfort when you walk. We will discuss the different types of data given in this paper.
