High aldehyde dehydrogenase activity at diagnosis predicts relapse in patients with t(8;21) acute myeloid leukemia.
Article in Cancer medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Acute myeloid leukemia (AML) with t(8;21) is a heterogeneous disease. Although the detection of minimal residual disease (MRD), which is indicated by RUNX1-RUNX1T1 transcript levels, plays a key role in directing treatment, risk stratification needs to be improved, and other markers need to be assessed. A total of 66 t(8;21) AML patients were tested for aldehyde dehydrogenase (ALDH) activity by flow cytometry at diagnosis, and 52 patients were followed up for a median of 20 (1-34) months. The median percentage of CD34+ALDH+, CD34+CD38-ALDH+, and CD34+CD38+ALDH+ cells among nucleated cells were 0.028%, 0.012%, and 0.0070%, respectively. The CD34+ALDH+-H, CD34+CD38-ALDH+-H, and CD34+CD38+ALDH+-H statuses (the percentage of cells that were higher than the individual cutoffs) were all significantly associated with a lower 2-year relapse-free survival (RFS) rate in both the whole cohort and adult patients (P = .015, .016, and .049; P = .014, .018, and .032). Patients with < 3-log reduction in the RUNX1-RUNX1T1 transcript level after the second consolidation therapy (defined as MRD-H) had a significantly lower 2-year RFS rate than patients with ≥ 3-log reduction (MRD-L) (P = .017). The CD34+ALDH+ status at diagnosis was then combined with the MRD status. CD34+ALDH+-L/MRD-H patients had similar 2-year RFS rates to both CD34+ALDH+-L/MRD-L and CD34+ALDH+-H/MRD-L patients (P = .50 and 1.0); and CD34+ALDH+-H/MRD-H patients had significantly lower 2-year RFS rate compared with CD34+ALDH+-L and/or MRD-L patients (P < .0001). Multivariate analysis showed that CD34+ALDH+-H/MRD-H was an independent adverse prognostic factor for relapse. In conclusion, ALDH status at diagnosis may improve MRD-based risk stratification in t(8;21) AML, and concurrent high levels of CD34+ALDH+ at diagnosis and MRD predict relapse.
