The main reasons for not recognising a systematic review as the basis for a PhD thesis in European biomedical graduate programs

Survey items Agree n (%) Neither agree nor disagree n (%) Disagree n (%) Don’t know n (%)
Systematic reviews are not a result of the candidate’s independent work since systematic reviews tend to be conducted by a team 41 (57.7%) 11 (15.5%) 11 (15.5) 8 (11.3%)
Systematic reviews do not produce enough new knowledge for a dissertation 38 (53.5%) 8 (11.3%) 20 (28.2%) 5 (7.0%)
Because of a concern arising when there are no primary studies available on a particular topic, or the inclusion criteria are too narrow (‘empty reviews’) 22 (31.0%) 26 (36.6%) 11 (15.5%) 12 (16.9%)
Systematic reviews are too easy to perform 22 (31.0%) 14 (18.7%) 31 (43.6%) 4 (5.6%)
There are no major differences between classical narrative and systematic reviews 14 (18.7%) 12 (16.9%) 37 (2.1%) 8 (11.3%)
Lack of expertise among committee members regarding systematic reviews, since they should be experienced in systematic review methodology 24 (33.8%) 22 (31.0%) 18 (25.4%) 7 (9.9%)
Lack of adequate training of candidates in methodology of systematic reviews 33 (46.5%) 19 (26.8%) 15 (21.1%) 6 (8.5%)
Students are not experienced enough to perform critical analysis of primary studies 31 (43.7%) 17 (23.9%) 18 (25.4%) 5 (7.0%)
Lack of appreciation of systematic review methodology among faculty members 25 (35.0%) 23 (32.0%) 18 (25.0%) 5 (7.0%)
