The first plastic bag includes the organ itself immersed in preservation solution (e.g. Celsior). This bag is put in a second bag filled with saline, and then these two are put in a third bag filled with saline which is then put in the ice box. The disadvantage of this method is that the organ usually gets too cold. It has been shown that the theoretical perfect temperature for organ preservation is 4°C - 8°C. While higher temperatures lead to hypoxic injury of the organ because the metabolism is not decreased efficiently, lower temperatures than 4°C increase the risk of cold injury with protein denaturation.

In addition, despite the sudden increase of publications concerning network meta-analysis, only a limited number focus on methodological and statistical aspects, and many issues remain unclear. The aim of our work was to explore and emphasize the potential attractiveness of network meta-analyses. We performed a systematic and narrative review (last updated on April 15, 2014) in order to assess the scholarly diffusion of network meta-analyses. The following data were collected: author identification, year and journal of publication, PubMed index, number of treatments and studies included, characteristics of network configuration, nature of primary outcome, clinical indication, type of intervention investigated and medical area. Since 2003 there has been an exponential increase in the number of published network meta-analyses. Out of 340 articles included according to our selection criteria, encompassing 248 treatment networks, cardiovascular and pulmonary diseases were the most prevalent topics, with an average of 5 treatments being compared stemming from an average of 10 controlled trials. In conclusion, network meta-analyses are becoming increasingly attractive as they offer a comprehensive framework for decision-making.
