Background: Controlled clinical trials (CCT) are the study design with the highest accuracy and evidence level. From its introduction in biomedical research, changes have been implemented in the way of establishing the basis for diagnosis, prognosis and treatment in clinical practice. Studies to identify published CCTs regarding different medical fields have been carried out. To date, none of them has identified the clinical trials that have been published in the Boletín Médico del Hospital Infantil de México (BMHIM). The aim of this study was to identify and describe the controlled clinical trials published in the BMHIM. Methods: A manual and systematic search was performed in each of the volumes of the BMHIM from 1968 to 2016. CCTs were recorded to obtain their main characteristics. Additionally, their methodological quality was assessed throu-gh the “risk of bias” tool. Results are presented in a descriptive, graphic and time-based manner. Results: In total, 73 issues with 363 volumes were reviewed, and 4925 articles were analyzed. The proportion of CCTs identified in the BMHIM was 1% (67/4925). In general, clinical trials were performed in the national context and in the third-level of medical care. CCTs also presented reduced sample sizes; pharmacological interventions were the most frequent. The methodological quality of the studies was low with a high risk of bias. Conclusions: Clinical trials represented 1% of all the original research articles published in the BMHIM. There are still pediatric research fields that require CCTs to be developed in order to improve clinical practice, as well as to increase the quality of the research.
