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
Sine oculis homeobox 4 (SIX4), a critical transcription factor modulating organ development, potentially participates in tumorigenesis through numerous pathways. Here, we investigated siRNA-mediated knockdown effects of SIX4 on pancreatic cancer cells and underlying molecular mechanisms. The expression of SIX4 in pancreatic cancer and adjacent tissues were investigated in clinical tissue samples and bioinformatically approved by gene expression omnibus (GEO) database. Appropriate siRNA transfected into PANC1 pancreatic cancer cells in order to SIX4 knockdown. The survival, migration, invasion, colony formation, mitochondrial membrane potential, apoptosis, autophagy, and cell cycle in the cancer cells were investigated after knockdown of SIX4. In addition, expression of genes involved in apoptosis and metastasis were assessed in the transfected cancer cells in mRNA and protein levels. High-throughput analysis using GEO database confirmed the overexpression of SIX4 in pancreatic cancer tissues by six independent pancreatic cancer microarrays. Knockdown of SIX4 by specific siRNA significantly decreased survival, colony formation, and mitochondrial membrane potential of the cancer cells. Further assessments demonstrated that knockdown of SIX4 increases the apoptosis and autophagy rates in the cancer cells through modifying the expression of related genes. Moreover, a significant decrease in migration and invasion rates were observed in SIX4 suppressed group. Furthermore, frequency of the cells transfected with SIX4 siRNA increased slightly in G1 and Sub-G1 phases of cell cycle. Our study suggested that siRNA-mediated knockdown of SIX4 increases the pancreatic cancer cells death and reduces the invasion and migration of the cancer cells through different molecular pathways.
