Prognostic value of serum progranulin in de novo adult acute myeloid leukemia patients.
Article in Hematology, transfusion and cell therapy. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundElevated serum progranulin (PGRN) levels have been associated with a wide range of different human malignancies. However, data available on the role of PGRN in hematological malignancies are limited.
methodsMeasurement of the PGRN level in serum of adult de novo acute myeloid leukemia (AML) patients using enzyme-linked immunosorbent assay (ELISA) was performed.
resultsThe mean serum PGRN level in AML patients was higher than that in controls (346.08 pg/ml ± 64.46 vs 155 pg/ml ± 63 respectively; p = 0.001). After a mean duration of follow-up equaling 140 days, patients with high serum PGRN (i.e., higher than 370.5 pg/ml) had inferior overall survival (OS) in comparison to patients with low serum PGRN (i.e., lower than 370.5 pg/ml) (OS = 25% vs 60.7%, mean survival = 107 days vs 256.5 days, p = 0.007). On the other hand, remitted patients on day 28 with high serum PGRN (i.e., higher than 307.5 pg/ml) did not differ from those with low serum PGRN (i.e., lower than 307.5 pg/ml) regarding disease-free survival (DFS) (DFS = 78.6% vs. 87.5%, mean survival = 301.3 days vs. 283.5 days, p = 0.789). Moreover, the serum PGRN level was associated with inferior OS (p = 0.024) on multivariate analysis.
conclusionAdult de novo AML patients have elevated serum PGRN levels and a high PGRN level is associated with an inferior OS.
