Motivated by the ongoing debate around transparency in empirical research and the reproducibility of scientific discoveries, this study aims to quantify the presence or absence of evidential value in published findings within the field of servitization research. Specifically, it evaluated whether the findings of published articles on the relationship between servitization and firm performance were free from p-hacking and selective reporting practices.

A total of 76 studied on this relationship were synthesized. For the main p-curve analysis, only one significant p-value was extracted from each article, ensuring compliance with the requirements of the p-curve method. Specifically, the analyzed p-values were independent of one another and exhibited a uniform distribution.

Both the main p-curve analysis results and robustness tests support the conclusion that this branch of the literature does have evidential value based on the published findings. Furthermore, approximately 60 studies included in the main p-curve analysis reported a significance level of p < 0.025 regarding the relationship between servitization and firm performance.

This research contributes to the ongoing debate on transparency in servitization research and advances the current understanding of the relationship between servitization and firm performance.

The aim was not to perform a systematic review but firstly to search in PubMed, Science Direct, Scopus and Web of Science databases on the papers published in the last five years using tools for reviewing the statement of preferred information item for systematic reviews without focusing on a randomized analysis and secondly to perform a bibliometric analysis on the properties of films and coatings added of tocopherol for food packaging.

On January 24, 2022, information was sought on the properties of films and coatings added of tocopherol for use as food packaging published in PubMed, Science Direct, Scopus and Web of Science databases. Further analysis was performed using bibliometric indicators with the VOSviewer tool.

The searches returned 33 studies concerning the properties of films and coatings added of tocopherol for food packaging, which were analyzed together for a better understanding of the results. Data analysis using the VOSviewer tool allowed a better visualization and exploration of these words and the development of maps that showed the main links between the publications.

In the area of food science and technology, the development of polymers capable of promoting the extension of the shelf life of food products is sought, so the knowledge of the properties is vital for this research area since combining a biodegradable polymeric material with a natural antioxidant active is of great interest for modern society since they associate environmental preservation with food preservation.
