Co-mutation of
Article in In vivo (Athens, Greece). 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
BACKGROUND/
aimMutations in the ASXL transcriptional regulator 1 (ASXL1) and splicing factor 3b subunit 1(SF3B1) genes are commonly observed in myeloid neoplasms and are independent predicative factors for overall survival (OS). Only a few contradictory reports exist on the clinical significance of concurrent ASXL1 and SF3B1 mutations. Previous studies also did not exclude patients with mutations of other genes, which could be confounding factors. MATERIALS AND
methodsWe identified 69 patients with mutation of only ASXL1, 89 patients with mutation of only SF3B1, and 17 patients with mutations exclusively of both ASXL1 and SF3B1 from our database of 8,285 patients and compared their clinical features and outcomes.
resultsPatients with ASXL1 mutations more frequently had acute myeloid leukemia (22.47%) or clonal cytopenia of unknown significance than patients with SF3B1 mutations (1.45%) or with ASXL1/SF3B1 mutations (11.76%). Patients with SF3B1 or ASXL1/SF3B1 mutations were more frequently diagnosed with myelodysplastic syndrome (75.36% and 64.71%, respectively) than patients with ASXL1 mutations (24.72%). Patients with ASXL1/SF3B1 (23.53%) mutations more frequently had myelodysplastic/myeloid proliferative neoplasm than did patients with ASXL1 mutations (5.62%) or with SF3B1 mutations (15.94%). OS of the ASXL1 mutation-only group was worse than that of the SF3B1 mutation-only group with a hazard ratio of 5.83 (p=0.017). Finally, and most importantly, the OS of the ASXL1/SF3B1 co-mutation group was poorer than that of both single-mutation groups (p=0.005).
conclusionASXL1/SF3B1 co-mutations portend worse OS than isolated ASXL1 or SF3B1 mutations, which might be due to abnormalities in both the epigenetic-regulatory and RNA-splicing pathways or because two genes instead of one are mutated.
