Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07273604). This is a study registration, not published results. Lead sponsor: Moisés Bermúdez Hernández. Recruitment status: COMPLETED. Phase: NA.

Brief summary: This study evaluated the efficacy of two structured psychological interventions in individuals with relapsing-remitting multiple sclerosis (RRMS). The main objective was to evaluate whether Group-Based Cognitive-Behavioral Therapy (CBT) and Psychophysiological Regulation Therapy (PRT) improved emotional well-being and objective cognitive functioning compared with Standard Care (SC). A total of 153 individuals with RRMS were assessed for eligibility, of whom 148 were randomized to one of three study conditions: Group-Based CBT, PRT, or SC (waiting-list control). Participants were allocated using a simple computer-generated randomization sequence with a 1:1:1 allocation ratio. Both active interventions were delivered in small groups over 12 weekly sessions. CBT and PRT shared a common therapeutic framework comprising psychoeducation, mindfulness, psychophysiological regulation strategies, and homework assignments. The CBT condition additionally incorporated specific cognitive-behavioral components during sessions 4-10. Assessments were conducted at baseline and immediately after completion of the 12-week intervention period using standardized psychological and neuropsychological measures. The study evaluated treatment effects across complementary domains of emotional functioning and objective cognitive performance.
