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 majority of colorectal cancers (CRCs) are hormone‑dependent. Thus, endocrine therapy has become an attractive strategy to treat CRC. The aim of the present study was to investigate the inhibitory effect of combined tamoxifen (TAM) plus β‑estradiol (E2) treatment on human DLD‑1 CRC cells. The human DLD‑1 CRC cell line was treated with different concentrations of TAM, β‑estradiol, or a combination of these two agents. Cell viability was assessed using an MTT assay, while apoptosis was detected using flow cytometry analysis. Alterations in the RNA and protein levels of the apoptosis‑associated factors cyclin D1 and survivin were measured in the treated DLD‑1 cells using semi‑quantitative polymerase chain reaction (sqPCR) and western blot analyses. Alterations in cellular migration ability were monitored using a Transwell migration assay. Treatment with TAM, β‑estradiol and TAM plus β‑estradiol inhibited DLD‑1 cell viability. The flow cytometry results revealed that these drugs promoted cell apoptosis, and the Transwell migration assay results indicated that the reduction in cell migration was greater in the TAM+E2 treatment group when compared with each treatment alone. sqPCR and western blot analysis results demonstrated that TAM, E2 and a combination of the two affected survivin expression based on the drug concentration and the treatment duration; however, they demonstrated no significant effect on cyclin D1 expression. In conclusion, treatment of DLD‑1 cells with TAM, β‑estradiol, or a combination of these two drugs, inhibited cell viability and migration, promoted cell apoptosis, and reduced the mRNA and protein expression levels of survivin in a dose‑ and time‑dependent manner. These results provide novel experimental basis for hormonal adjuvant therapy for the treatment of CRC.
