Medical field is abuzz with artificial intelligence, that is disrupting health care by transforming its many aspects from image analysis and drug discoveries to patient monitoring, to healthcare operations and public health initiatives. In clinical research, this impact is felt through the steady increase in the number of clinical prediction models, proclaiming novel predictors and promising superior accuracy, intuitive use, and drastic improvements in patient outcomes and resource allocation. This increase is due not only to growing availability of healthcare data and developments in analysis methodology, but also, and in no small part, to advances in modern software lowering the barriers to entry. The democratization of technology and the advancement of user-friendly tools are allowing researchers with varying skill sets to try their luck in developing clinical prediction models.

We conducted a systematic review of research publications in PubMed 2018 – 2023 in the field of heart failure that were presented as developing clinical prediction models by their authors. The abstracted data elements were based on those identified in PROBAST (Prediction model Risk of Bias ASsessment Tool) and TRIPOD (Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis). We evaluate the methodological conduct of the studies and present the sentiment analysis to estimate the prevalence of subjective or promotional language in the abstract corpus.
