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
Lidamycin (LDM, also known as C-1027) as an anti-cancer agent inhibits growth in a variety of cancer cells by inducing apoptosis and cell cycle arrest. In this study we demonstrated that inhibition of mouse embryonic carcinoma (EC) cell growth using LDM at low concentrations can be attributed to a loss of the cell's self-renewal capability but not to apoptosis or cell death, which can be correlated to the down-regulation of embryonic stem (ES) cell-like genes Oct4, Sox2 and c-Myc. MTT assays showed that LDM inhibited the growth of mouse P19 EC cells in a time- and dose-dependent manner. The EC cells exposed to a low dose (0.01 nM) of LDM lost their capability to generate colonies, as evidenced by the colony forming assay. Flow cytometer analyses demonstrated that LDM induced G1 arrest in exposed EC cells without apoptosis. Real-time qPCR, Western blotting and immunocytochemistry revealed that Oct4, Sox2 and c-Myc were down-regulated in LDM-exposed EC cells, but not adriamycin (ADM)-exposed cells. Furthermore, a combination of the low dose of LDM and ADM significantly reduced the proliferation of the cancer cells than single-agent treatment. This suggested that synergy of ADM and LDM improved chemotherapy. Taking together, our results indicate that LDM can reduce the capability for self-renewal that mouse EC cells possess through the repression of ES cell-like genes, thereby inhibiting carcinoma cell growth. This data also suggests that LDM might have potential for application in CSC-based therapy and be a useful tool for studying ES cell pluripotency and differentiation.
