Unveiling the Prognostic Power of Circulating Tumor DNA in Multiple Myeloma: A Systematic Review and Updated Meta-Analysis.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Circulating tumor DNA (ctDNA) serves as a non-invasive liquid biopsy technique, offering potential utility in the prognostic evaluation of multiple myeloma (MM). In this study, we performed a systematic review and updated meta-analysis to analyze the association between ctDNA and the prognosis of patients diagnosed with MM. A comprehensive literature search was performed across PubMed, Embase, Web of Science, and the Cochrane Library to retrieve relevant literature published up to May 29, 2025, assessing the impact of ctDNA on survival outcomes in patients with MM. The survival outcomes included overall survival (OS), progression-free survival (PFS), and time to progression (TTP). A total of 948 MM patients from 14 studies were included in the analysis. Patients with detectable ctDNA exhibited a significantly increased risk of aggressive disease progression (hazard ratio [HR], 3.21; 95% confidence interval [CI], 1.98-5.18) and reduced OS (HR, 3.97; 95% CI, 2.24-7.04). Subgroup analyses consistently indicated that ctDNA positivity was associated with accelerated disease progression, irrespective of race, disease status, treatment, or ctDNA detection method. In subgroups defined by relapsed or refractory MM (RRMM) and Oceanian or Caucasian race, ctDNA positivity was significantly correlated with poorer OS. However, the associations were not significant in newly diagnosed MM (NDMM) or among Asian patients. Therefore, we conclude that ctDNA is a potential predictor of inferior survival outcomes in MM patients.
