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 activation of the phosphatidylinositol-3 kinase/v-akt murine thymoma viral oncogene homolog (Akt) and mitogen activated protein kinase kinase/extracellular signal-regulated kinase (ERK) pathways are implicated in the majority of cancers. Selective inhibition of Akt and ERK represents a potential approach for cancer therapy. Therefore, the present study aimed to investigate the apoptotic and anti-proliferative effects of the novel and selective Akt inhibitor 4-amino-5,8-dihydro-5-oxo-8-β-D-ribofuranosyl-pyrido[2,3-d]pyrimidine-6-carboxamide (API-1) and selective ERK1/2 inhibitor FR180204 (FR) alone and in combination on colorectal cancer (CRC) cells (DLD-1 and LoVo). In addition, the effects of API-1 and FR on Akt and ERK signaling pathways were also investigated. The effects of the agents on DLD-1 and LoVo cells were evaluated in terms of cell viability, cytotoxicity, DNA synthesis rate, DNA fragmentation and caspase-3 activity levels. In addition, quantitative reverse transcription-polymerase chain reaction and western blot analysis were performed to examine relevant mRNA and protein levels. The present study observed that the combination of FR with API-1 resulted in significant apoptosis and cytotoxicity compared with any single agent alone in a time-dependent manner in these cells. Also, treatment with FR and API-1 in combination decreased the expression levels of B-cell lymphoma-2 (BCL2), Bcl-2-like1, cyclin D1 and cMYC, and increased the expression levels of BCL2-associated X protein and BCL2 antagonist/killer via phosphorylated Akt and phosphorylated ERK1/2 downregulation. The combination of Akt and ERK1/2 inhibitors resulted in enhanced apoptotic and anti-proliferative effects against CRC cells. The present study hypothesizes that the combination of FR and API-1 in CRC cells may contribute toward potential anti-carcinogenic effects. Additional analyses using other cancer cell lines and animal models are required to confirm these findings
