SECTM1-based CAR T cells enriched with CD7-low/negative subsets exhibit efficacy in CD7-positive malignancies.
Article in Blood advances, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
CD7 has been found to be a promising chimeric antigen receptor (CAR) T cell target in several clinical trials. However, its expression on normal T cells poses additional challenges in CD7-directed CAR therapy, such as complete fratricide, contamination with malignant cells, and immune suppression due to T-cell aplasia. By taking advantage of evolved affinity between ligand and receptor, we constructed a CD7-directed CAR with the extracellular domain of SECTM1, a natural ligand of CD7, as the recognition domain. SECTM1 CAR T cells killed the majority of T cells with high CD7 expression in vitro. However, SECTM1 CAR T cells with low or negative CD7 expression survived, expanded, and showed strong cytotoxicity to CD7+ malignant cell lines and primary leukemic blasts from patients with T-cell acute lymphoblastic leukemia and acute myelogenous leukemia in vitro. It also exhibited efficacy in inhibiting xenograft tumor growth in vivo. More exploration is needed for clinical efficacy potential to patients with CD7+ malignancies.
