*3.5. Comparing Results with Other Methods*

Some bibliographic reviews similar to this one have already been carried out. They have focused on other indirect and semi-direct assessment methods. Some matches are presented in the results obtained.

The RULA method matches the OWAS method and the Standardized Nordic Questionnaire in the most common knowledge categories. The field of industry and health and social assistance are the most researched, with one or the other being highlighted depending on the method [8,260]. The REBA method has also been highlighted in industry, although the health-related field ranks fourth [261].

For countries with the highest number of publications, none of the methods coincided with RULA, since REBA excelled in India, OWAS in Finland and the Nordic Questionnaire in Iran. However, for REBA, the second country with the most studies was the USA [8,260,261].

By date, the Nordic Questionnaire matches RULA. The year 2016 was when more studies were published for both [260].

Finally, with regards to journals, information is only available for the REBA method. The journal with the largest number of publications on this method is "Work—A Journal of Prevention Assessment & Rehabilitation"; this is also the case for RULA [261].

It should be noted that this comparison is general since the date range selected in each of the studies is not the same.
