1 · What the graph read from it

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.

2 · The registry

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

Annexin I is a phospholipid and actin binding protein which may play a role in signal transduction to the cytoskeleton. Previous work reported the differential expression of annexin I mRNA among rat adenocarcinoma cell lines of various metastatic potential (MTLn3, MTLn2, MTC.4: highest to lowest, respectively) (Pencil et al. 1993, Breast Cancer Res Treat, 25, 165-74). This relationship has been extended to the protein level in in vitro cultures using Western blotting and flow cytometry. Annexin I protein levels in MTLn3 cells are 3- to 5-fold higher than in MTC.4 cells. The weakly metastatic cell line MTLn2 shows levels 1.5- to 2.5-fold higher than MTC.4. In vivo tumors were produced by injecting 1 x 10(6) cells into mammary fat pads of syngeneic rats and necropsies were performed 40 days later. Semiquantitative immunohistochemical color image analysis was performed using a polyclonal rat annexin I specific antibody. Annexin I protein expression was highest in lung metastases of MTLn3, at 8-fold the levels observed in the MTC.4 primary tumors. MTLn3 cells in the primary tumor had an annexin I specific optical density 3-fold higher than that of cells in the MTC.4 primary tumor. MTLn2 primary tumors had an annexin I specific optical density 1.5-fold higher than MTC.4. A proportion of human mammary adenocarcinomas also have positive annexin I immunoreactivity, often with more uniform annexin I staining in the lymph node metastases. These results suggest that there may be survival advantages for nascent metastatic cells with high annexin I levels.
