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
aimThis study explores the prognostic impact of FLT3-ITD, NPM1, and WT1 mutations both independently and in combination in Cytogenetically Normal Acute Myeloid Leukemia (CN-AML) patients as they exhibit varying clinical outcomes.
methods150 CN-AML patients were selected to assess the prevalence and prognostic significance of WT1 mutations in combination with FLT3-ITD and NPM1 status using polymerase chain reaction (PCR) followed by Sanger sequencing.
resultsWT1 exon 7 mutations were present in 12.6% of patients. Elderly individuals, with a mean age of 49.4 years, were more prone to NPM1 mutations, though the association was not statistically significant (p=0.094). Significant associations were observed between lactate dehydrogenase (LDH) and hemoglobin (Hb) levels with FLT3-ITD and NPM1 mutations (p=0.003 and p=0.04, respectively). The M4 subtype exhibited the highest prevalence of WT1 mutations (p=0.0036). Patients with NPM1 mutations had a higher overall survival rate compared to NPM1 wild-type cases (p=0.057). There was no significant correlation between overall survival and WT1 and FLT3-ITD mutations. Regarding relapse-free survival, NPM1 mutation cases exhibited a higher survival probability compared to NPM1 wild-type cases. Similarly, WT1 mutated cases had a higher survival probability compared to WT1 wild-type cases, although these differences were not statistically significant. The combined mutation statuses of NPM1/FLT3-ITD with WT1 did not yield significant outcomes. The study suggests that larger cohort studies may reveal more relevant associations, given the relatively small cohort in this study.
conclusionThis study found a significant association between patient survival outcomes and NPM1 mutation status, as well as the combined FLT3-ITD and NPM1 status. Profiling both NPM1 and FLT3-ITD mutations at the time of diagnosis serves as a robust prognostic marker in AML treatment. WT1 mutation status did not show a significant association with patient outcomes. Larger population studies may provide more relevant insights.
