1 · What the graph read from it

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.

2 · The registry

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

Chimeric antigen receptor T-cell (CAR-T) therapy has transformed treatment paradigms for relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (B-ALL) in children and younger adults. We performed a systematic review to investigate the published literature on efficacy and toxicity of CAR-T therapy in adults with r/r B-ALL. We searched MEDLINE, Embase, and the Cochrane Library for prospective interventional studies and included published studies of ≥5 patients with median age at enrollment of ≥18 years. Risk of bias was assessed with a modified Institute of Health Economics tool. A total of 2566 records were assessed; 16 studies involving 489 patients were included in the final analysis. The mean complete remission (CR) rate was 81% and the measurable residual disease (MRD)-negative remission rate was 81% at 4 weeks after CAR-T infusion. With median follow-up across studies of 24 months, the cumulative 12-month probabilities of progression-free survival (PFS) and overall survival (OS) were 37% (95% CI, 26-48) and 57% (95% CI, 49-65), respectively. Relapse occurred in 40.3% of cases; target antigen was retained in 73.2% of relapses. Across studies, any grade of cytokine release syndrome (CRS) occurred in 82% of patients (95% CI, 61-95) and grade 3 or higher CRS in 27% (95% CI, 18-36). Neurotoxicity of any grade occurred in 34% of patients (95% CI, 24-47) and grade 3 or higher in 14% (95% CI, 1-25). In summary, CAR-T therapy achieves high early remission rates in adults with r/r B-ALL and represents a significant improvement over traditional salvage chemotherapy. Relapses are common and durable response remains a challenge.
