Sociodemographic, Clinical, and Therapeutic Characterization of Multiple Myeloma Patients (CharisMMa Study) with Symptomatic Relapse and/or Refractory Disease: An Observational, Multicenter Study in Portugal.
Article in Hematology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04135963 (Clinical and Sociodemographic Characterization of Multiple Myeloma Patients With Symptomatic Relapse and/or Refractory Disease in Portugal), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
objectivesReal-world information on relapsed and/or refractory multiple myeloma (rrMM) clinical management in Portugal is scarce. The CharisMMa Portugal study aimed to characterize rrMM patients through socio-demographic and clinical parameters and describe treatment patterns.
methodsThis was an observational, cross-sectional, multicenter study with 62 rrMM patients routinely treated at seven hospitals in Portugal. Data were collected from medical records during clinical appointments (2020-2022) after written informed consent was obtained (ClincialTrials.gov ID-NCT04135963). Patients who were diagnosed with a symptomatic MM episode in the 6 months prior to study initiation and who received treatment before their last relapse episode were enrolled.
resultsMost patients were male (54.8%) and living with relatives (90.3%), and almost 50% were independent. Roughly 70% of patients were classified as Revised MM International Staging System (R-ISS) Stage II at diagnosis, with a mean age of 65.76 (±9.24) years old. Most common SliM-CRAB (SLIM: sixty percent or more clonal plasma cells in the bone marrow (S), light chain ratio ≥100 (Li), and MRI-detected focal lesions (M); CRAB: hypercalcemia (C), renal insufficiency (R), anemia (A), and bone lesions (B)) signs were bone lesions (59%), and 62.9% of the patients had at least one comorbidity. At study initiation, 70.5% of patients were on second-line treatment, with monoclonal antibodies and proteasome inhibitors (PIs) + immunomodulators (IMiDs) as leading agents. Triplet regimens were the most common across all lines, while oral and oral + subcutaneous were the most prevalent routes of administration.
conclusionsTriple treatment combinations are common in rrMM management, with PIs and IMiDs frequently used, especially in first-line settings. The use of oral formulation is substantial, suggesting a step toward more patient-centric options. This characterization underscores the complexity of rrMM management and should inform stakeholders of strategies to standardize patient care across reference centers in Portugal.
