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
Although dephosphorylation of tyrosine containing proteins is considered a necessary step in the induction of leukemia cell differentiation by hybrid polar compounds (HPC), the crucial actors in this step remain unknown. We present evidence that tyrosine phosphorylation of JAK1 and JAK2 is down-regulated in murine erythroleukemia cells (MELC) within the first 6 h of their exposure to the prototype of the HPC family, hexamethylenebisacetamide (HMBA), with full recovery at 14 h. Further evidence that the JAKs-centered signalling pathway is switched off early by HMBA was provided by the demonstration that STAT5, a downstream member of this pathway, turned out to be completely dephosphorylated at 6 h in HMBA-treated cells. This JAKs dephosphorylation did not occur in HMBA-resistant clones, suggesting that JAKs are possible targets of the dephosphorylative process required for leukemia cell commitment to differentiation. These results may have impact on leukemia therapy based on JAKs inhibitors.
