Altered leukotriene B4 levels by HL-60 cells after monocytic/macrophage differentiation.
Article in Agents and actions, 1993. 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
The differentiation of HL-60 human promyelocytic leukaemia cells into specific monocytic or granulocytic lineage cells depending of the inductor agent is accompanied by selective regulation of several key enzymes involved in the synthesis of eicosanoids. In this communication we have investigated the changes in arachidonic acid metabolic profiles during phorbol 12-myristate 13-acetate (PMA)-induced monocytic differentiation of HL-60 cells. Our results show that HL-60 cells have spontaneous capacity to synthesize large amounts of LTB4, but PMA-differentiated cells lose the ability to release LTB4. Significant differences are found between HL-60 cells and PMA-treated cells in basal conditions and under ionophore stimulation. The addition of LTB4 at the time of PMA differentiation did not have effects on cell proliferation, but nordihydroguaiaretic acid (NDGA), a potent 5-lipoxygenase inhibitor, also inhibited HL-60 cell proliferation and did not have any effect on PMA-differentiated cell proliferation.
