K+ channel antisense oligodeoxynucleotides inhibit cytokine-induced expansion of human hemopoietic progenitors.

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
Primitive human hemopoietic progenitor cells identified by surface membrane markers CD33-CD34+ are capable of expansion into lineage-restricted precursors following in vitro stimulation by hemopoietic regulators such as stem cell factor (SCF) and interleukin-3 (IL-3). In search of ionic currents involved in cytokine-induced progenitor cell growth and differentiation, human umbilical cord blood CD33-CD34+ cells were subjected to perforated patch-clamp recordings following overnight incubation with SCF and/or IL-3. An inward rectifying potassium channel (Kir) was found in 33% of control unstimulated cells, in 34% of cells incubated with IL-3, in 31% of cells incubated with SCF and in 75% of cells incubated with IL-3 plus SCF. Kir activity increased with elevation of extracellular potassium and was blocked by extracellular Cs+ or Ba2+ Antisense oligodeoxynucleotides directed against Kir blocked both mRNA and functional expression of Kir channels. Kir antisense also inhibited the in vitro expansion of cytokine-stimulated CD33-CD34+ cells into erythroid (BFU-E) and myeloid (GM-CFU) progenitors in 7-day suspension cultures. Extracellular Cs+ or Ba2+ induced a similar degree of inhibition (40-60%) of progenitor cell generation. These findings strongly suggest an essential role for Kir in the process of cytokine-induced primitive progenitor cell growth and differentiation.
