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 purpose of the present study was to evaluate cimigenol (Cim) treatment effects to cell proliferation by breaking bone marrow stromal cells (BMSCs) through C-X-C chemokine receptor type 4 (CXCR4)/stromal cell-derived factor-1α (SDF-1α) pathway. MV-4-11 and U937 cell lines were used. The present study was divided into two parts. First, the cell lines were divided into normal control (NC), BMSC (cells co-cultured with BMSCs), BMSC + DMSO, BMSC + Low (treated with 5 mg/ml Cim), BMSC + Middle (treated with 10 mg/ml Cim), BMSC + High (treated with 20 mg/ml Cim). In the second step, the cell lines were divided into NC, BMSC, BMSC + BL8040 (treated with BL8040 which inhibits CXCR4), BMSC + Cim and BMSC + Cim + BL8040. EdU positive cell numbers were measured by EdU assay and apoptosis rate by flow cytometry and TUNEL assay. Relative gene and protein expression was measured by reverse transcription-quantitative PCR and western blotting assay. BMSCs were able to protect proliferation of cancer cells and decreased cell apoptosis compared with the NC group (P<0.001, respectively). With Cim supplement, the cell proliferation was decreased with cell apoptosis increasing compared with NC group (P<0.001 respectively). However, the anti-tumor effects of Cim were not significantly different from the BL8040 treated groups (P<0.001, respectively). In conclusion Cim decreased acute myeloid leukemia cells protected by BMSCs through the CXCR4/SDF-1α pathway.
