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
HMMC-1 is a human monoclonal antibody that reacts with a fucosylated and extended core 1 O-glycan, Fucα1-2Galβ1-4GlcNAcβ1-3Galβ1-3GalNAc-Ser/Thr, as an epitope. In the present study, we examined the effects of HMMC-1 on cell proliferation of two human uterine endometrial cancer cell lines, HEC8 and HEC9, to investigate the role of glycoproteins bearing the HMMC-1 epitope in cancer progression. HEC9 cells expressed high levels of the HMMC-1 epitope, but HMMC-1 reactivity was hardly detected in HEC8 cells. In a mouse model of lymph node metastasis using orthotopic implantation, HEC8 and HEC9 showed low (10%) and high (80%) metastatic potency, respectively. Growth of HEC9, but not HEC8, was remarkably inhibited by addition of HMMC-1 to the culture medium. Cell cycle analysis and expression analysis showed that HMMC-1 treatment increased the G(1) phase population of HEC9 cells and induced cyclin-dependent kinase inhibitors p16 and p21. Two glycoproteins, 97 and 137 kDa, with a strong reactivity to HMMC-1 were purified, and the 97-kDa glycoprotein was identified as CD166, an immunoglobulin superfamily cell adhesion molecule assumed to be involved in cancer metastasis. CD166 gene-silencing dramatically reduced HMMC-1 epitope expression and growth in HEC9 cells, indicating that CD166 is the primary glycoprotein presenting the HMMC-1 epitope in HEC9 cells. Collectively, HMMC-1 might arrest the cell cycle in the G(1) phase by binding to O-glycans on the CD166 expressed in HEC9 cells, raising the possibility that HMMC-1 extensively inhibits invasive growth of HMMC-1 epitope-positive uterine endometrial cancer cells by targeting the cancer-associated form of CD166.
