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

objectiveTo evaluate the expression of PD-L1 (programmed death 1 ligand 1, PD-L1) and its clinical significance in breast invasive ductal carcinoma.

methodsTumor samples were collected from 64 cases of breast invasive ductal carcinoma patients, and tumor adjacent normal breast tissue were obtained as normal control. The expression of PD-L1 were examined by immunohistochemical staining and real time PCR assay, its correlations with patients' clinical pathological characteristics were analyzed.

resultsPD-L1 was found to be over-expressed in 24 of 64 (37.5%) breast invasive ductal carcinoma samples, while in 1 of 22 (4.5%) tumor adjacent normal breast tissue which indicated PD-L1 was higher expressed in breast invasive ductal carcinoma samples than the tumor adjacent normal breast tissue (P < 0.05). PD-L1 positive expression was associated with clinical pathological characteristics of TNM stage and pathology grading (P < 0.05). However, PD-L1 positive expression was not correlated with age (P > 0.05), menstruation status (P >0.05), family history of breast cancer (P > 0.05), tumor diameter (P > 0.05), lymph node metastasis (P > 0.05) and tumor location (P > 0.05).

conclusionPD-L1 may play an important role in invasive ductal carcinoma, which could be a potential indicator for advanced clinical stage and poor prognosis.
