“…1, all studies but one [29] reported data on LOS, while data on in-hospital mortality were reported in 23 studies [16, 20, 22-25, 27, 31-33, 35-38, 43-46, 48-52]. In contrast, only about half of the studies reported data on TTS [21-25, 30, 32-35, 38, 39, 42-47, 51], complication rates [17, 20, 22, 25, 28, 32, 33, 35-39, 41, 43-45, 47, 51], and 1-year mortality [18,27,31,32,35,38,39,41,42,44,[47][48][49][50]. 30-day readmission rate [18,33,35,37,41,45], functional outcomes [18, 21-23, 27, 34], and cost [21,26,29,31,40] were reported in less than a quarter of the studies.…”
