*Strengths and Limitations*

Evidence maps represent a novel approach that can be employed to detect broader issues, lead to research synthesis, and guide researchers in formulating both future research and studies with a narrower focus [42,43]. Evidence maps have been especially helpful in visualizing research contexts and appreciating how a specific focus fits into the broader research field [44]. In the case presented here, the evidence map aids in understanding how TBI research fits within the context of clinical research and where it stands overall in the field of rehabilitation.

A limitation that requires some discussion pertains to the search strategy. This overview exclusively analyzed systematic reviews published in the Cochrane library, which may have limited the inclusion of other high-quality systematic reviews on TBI. Nevertheless, Cochrane suggests this approach to preserve consistency in the results of the overview since the included works follow the same methodological standard [45].

We acknowledge that the evidence map developed for TBI is unable to address specific questions or nuances regarding the effectiveness of rehabilitation interventions in individuals with TBI.

Despite its limitations, the evidence map we have constructed disseminates evidence from existing literature findings on TBI, draws attention to the current challenges faced by researchers, and can provide an effective tool in guiding future research efforts and policymaking.

#### **5. Conclusions**

This work clarifies the need to expand research efforts in the context of TBI and clinical rehabilitation research to augment clinical applicability. In general, patients receiving rehabilitation services display a broad range of deficits and needs, which is particularly apparent among patients with TBI. Currently, the efficacy and safety of non-pharmacological and pharmacological interventions that are able to meet the needs of individuals with TBI remain uncertain, jeopardizing the clinical applicability of potentially effective interventions. To address the challenges experienced in clinical rehabilitation research, increasing the number of clinical and non-clinical trials performed that reflect sound methodology remains a priority.
