Fig. 2 – Quality assessment of preclinical and clinical studies. All studies included for meta-analysis were scored on clear reporting of several key
parameters (Q1–Q21) showing that study design such as inclusion of proper control groups, associated randomization and blinding, reporting of key
parameters such as representativeness of shown results, and drop-outs needs to be improved in preclinical studies.
N/A = not applicable; Q = question.
