1 · What the graph read from it

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.

2 · The registry

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

Programmed death ligand 1 (PD-L1) is a trans-membrane protein that can reduce the immune response in both infectious diseases and cancers and is commonly expressed in various solid tumors. Despite the success of immunotherapy directed at inhibiting of PD-L1/PD-1 signaling, it is not established that whether PD-L1 expression correlates with the clinical response and outcome in cervical squamous cell carcinoma. To investigate the clinical significance of PD-L1 expression in cervical cancer, we analyzed the expression of PD-L1 in 219 cervical squamous cell cancers and 30 healthy controls,characterized the expression level of PDL-1 in tumor-infiltrating lymphocytes (TILs), and assessed the relationship between them and prognosis of cervical cancers. The expression of PD-L1 was observed in 32.4% (71/219) cervical carcinomas and 10.0% (22/219) in partial TILs. However, there was no expression of PD-L1 in normal cervical epithelium. Statistical analysis showed that increased PD-L1 expression was significantly associated with high TNM stage, reduced number of TILs, and worse prognosis in cervical carcinomas, but there was no significant statistic difference in age, tumor size, HPV infection and other clinicopathology features. PD-L1 expression in TILs was found significantly associated with the TILs amount. Furthermore, the presence of prominent lymphocytic infiltrates was also significantly associated with a clear trend towards longer survival. In conclusion, these data suggested that PD-L1 could act as a significant biomarker in the worse prognosis and adverse clinicopathologic features of cervical cancer. Anti-PD-L1 therapy may have a role in the treatment of cervical squamous cell carcinoma.
