Conclusions Oral TRT produces significant CV risk .
Differences in the degree to which serum DHT is elevated may underlie the varying CV risk by TRT administration route , as elevated serum dihydrotestosterone has been shown to be associated with CV risk in observational studies
Background Potential cardiovascular ( CV ) risks of testosterone replacement therapy ( TRT ) are currently a topic of intense interest .
However , no studies have addressed CV risk as a function of the route of administration of TRT .
The Delphi list: a criteria list for quality assessment of randomized clinical trials for conducting systematic reviews developed by Delphi consensus.
Most systematic review s rely substantially on the assessment of the method ological quality of the individual trials . The aim of this study was to obtain consensus among experts about a set of generic core items for quality assessment of r and omized clinical trials ( RCTs ) . The invited participants were experts in the field of quality assessment of RCTs . The initial item pool contained all items from existing criteria lists . Subsequently , we reduced the number of items by using the Delphi consensus technique . Each Delphi round comprised a question naire , an analysis , and a feedback report . The feedback report included staff team decisions made on the basis of the analysis and their justification . A total of 33 international experts agreed to participate , of whom 21 completed all question naires . The initial item pool of 206 items was reduced to 9 items in three Delphi rounds . The final criteria list ( the Delphi list ) was satisfactory to all participants . It is a starting point on the way to a minimum reference st and ard for RCTs on many different research topics . This list is not intended to replace , but rather to be used alongside , existing criteria lists
