Stem cell therapy for non-ischemic dilated cardiomyopathy: a systematic review and meta-analysis.
Synthesis in Systematic reviews, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundStem cell therapy is the transplantation of human cells to aid the healing of damaged or wounded tissues and cells. Only a few small-scale trials have been conducted to investigate stem cell therapy for non-ischemic dilated cardiomyopathy (DCM). We aimed to perform a systematic review and meta-analysis to assess the efficacy and safety of stem cell therapy for DCM.
methodsA comprehensive search of the databases of PubMed, Embase, Web of Science Core Collection, Cochrane Library, and ProQuest was conducted from their inception to June 30, 2024, to access randomized controlled trials (RCTs) that were centered on stem cell therapy for DCM. The primary outcome was left ventricular ejection fraction (LVEF), and the secondary outcomes included left ventricular end-diastolic dimension (LVEDD), left ventricular end-diastolic volume (LVEDV), 6-min walk test (6MWT), NYHA functional classification, quality of life (QoL) such as Minnesota Living with Heart Failure Questionnaire (MLHFQ) and Kansas City Cardiomyopathy Questionnaire (KCCQ), N-terminal pro-brain natriuretic peptide (NT-proBNP), and VO
resultsEleven RCTs involving 637 participants were included in the quantitative analysis. The results indicated that there was a significant increase in mean LVEF (MD = 4.84, 95% CI 3.25-6.42, P < 0.00001) and considerable decrease in LVEDV (MD = - 29.51, 95% CI - 58.07 to - 0.95, P = 0.04) and NT-proBNP (MD = - 737.55, 95% CI - 904.28 to - 570.82, P < 0.00001) in DCM patients treated with stem cell therapy compared with controls. Stem cell therapy was also related to the improvement in functional capacity, as evaluated by 6MWT (MD = 44.32, 95% CI 34.70 - 53.94, P < 0.00001) and NYHA functional classification (MD = - 0.63, 95% CI - 0.96 to - 0.30, P = 0.0002). It also had positive effects on improving QoL, including significantly decreasing MLHFQ score (MD = - 16.60, 95% CI - 26.57 to - 6.63, P = 0.001) and increasing the KCCQ score (MD = 14.76, 95% CI 7.76 - 21.76, P < 0.0001). No significant differences were observed in LVEDD, VO
conclusionThe systematic review and meta-analysis indicates that stem cell therapy may be an effective and safe approach to improve cardiac function and quality of life in DCM patients. Nevertheless, given the limitations of existing studies, larger well-designed RCTs are required to confirm and support our findings.
