Chimeric antigen receptor modified T cells directed against CD19 (CTL019) in patients with relapsed, refractory CLL: a systematic review and meta-analysis.
Review in American journal of blood research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesChronic lymphocytic leukemia (CLL) is a hematologic malignancy characterized by the excessive production of lymphocytes in the bone marrow. One of the emerging therapeutic strategies for CLL is chimeric antigen receptor (CAR) T-cell therapy, wherein T-cells are genetically modified to recognize and target cancer cells more effectively. The present study aims to systematically compare the therapeutic impact of high-dose versus low-dose status of CAR T-cell therapy targeting CD19 (CART-19) in patients with relapsed or refractory CLL.
methodsTo identify relevant studies, a comprehensive literature search was conducted in PubMed, Scopus, and Web of Science databases up to April 2023. The primary outcome measures included treatment response rates, assessed as complete response (CR) and partial response (PR), and toxicity, as indicated by the incidence of cytokine release syndrome (CRS). Additionally, sensitivity and bias analyses were performed to evaluate the robustness of the findings.
resultsFour randomized controlled trials (RCTs) comprising 89 patients with relapsed or refractory CLL met the inclusion criteria. Comparison of treatment response rates between high-dose and low-dose CART-19 therapy demonstrated a significantly higher complete and partial response rate in the high-dose group (SMD [95% CI]: 1.02 [0.10, 1.94]; P<0.05). However, no significant association was observed between CTL019 dosage and the incidence of CRS (P>0.05).
conclusionThis meta-analysis suggests that high-dose CART-19 is associated with improved response rates and survival outcomes in patients with CLL compared to low-dose therapy. However, due to variability in study results, further large-scale, well-designed trials are required to establish the optimal therapeutic dosing strategy for CART-19 therapy in CLL.
