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
This study investigates the interrelationship between human telomerase reverse transcriptase (hTERT) and ferroptosis in precursor-B (pre-B) acute lymphoblastic leukemia (ALL), specifically examining how hTERT modulation affects ferroptotic cell death pathways. Given that hTERT overexpression characterizes various cancer phenotypes and elevated telomerase activity is observed in early-stage and relapsed ALL, we investigated the molecular mechanisms linking hTERT regulation and ferroptosis in leukemia cells. The experimental design employed Nalm-6 and REH cell lines under three distinct conditions: curcumin treatment, hTERT siRNA knockdown, and their combination. Cell viability and proliferation were assessed via MTT and BrdU assays at 24- and 48-hour intervals post-treatment. Ferroptotic and oxidative markers were quantified using commercial assays, while cell death parameters and gene expression were evaluated through flow cytometry and qRT-PCR analyses. Molecular docking studies were performed to evaluate protein-ligand interactions. Results demonstrated that combined curcumin treatment and hTERT knockdown significantly enhanced cytotoxicity in Nalm-6 cells compared to individual interventions. This was characterized by the upregulation of ferroptosis promoters (lipid-ROS, Fe²⁺, ACSL4) and suppression of inhibitors (GSH, GPx, SLC7A11, GPx4). The response showed cell-line specificity, with Nalm-6 cells exhibiting enhanced ferroptotic sensitivity while REH cells underwent apoptotic cell death. Molecular docking revealed strong curcumin-protein interactions (∆G = -34.24 kcal/mol for hTERT). This study establishes hTERT as a critical regulator of ferroptotic cell death in pre-B ALL, operating through redox homeostasis, iron metabolism, and lipid peroxidation pathways. The cell-type-specific responses suggest promising therapeutic strategies through combined hTERT suppression and ferroptosis induction.
