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
Cervical cancer is the fourth most common cancer and the fourth leading cause of cancer death in women. Human papillomavirus (HPV16) E6/E7 heterogenous expression in C33A cells increased the mRNA and protein levels of KIF2A, while siRNA deletion of endogenous E6/E7 reduced the mRNA and protein levels of KIF2A in SiHa cells. KIF2A promoted cell migration and invasion, and regulated the expression of epithelial-mesenchymal transition-related proteins in C33A and SiHa cells. The exogenous expression of E6/E7 in C33A cells increased the phosphorylation of Akt, ERK, and JNK. However, Akt (API-2) and ERK (PD98059) inhibitors had no effect on the increase in KIF2A expression induced by E6/E7, while JNK inhibitors (JNK-IN-8 and SP600125) blocked the increase in KIF2A expression induced by E6/E7. The exogenous expression of E6/E7 increased the levels of transcription factor c-Jun, which is the classic substrate of JNK. Knockdown of c-Jun reduced the increase in KIF2A expression induced by E6/E7. In summary, KIF2A plays a key role in the motility and metastasis of cervical cancer. HPV16 E6/E7 can increase the levels of transcription factor c-Jun by activating the JNK signal, thereby up-regulating the transcriptional expression of KIF2A.
