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 explore the correlation of PD-1/PD-L1 polymorphisms and their expressions with clinicopathologic features and prognosis of ovarian cancer.

methodsA total of 164 patients with ovarian cancer were enrolled as case group and 170 healthy women as control group. We conducted quantitative reverse transcription-PCR (qRT-PCR) to determine PD-1/PD-L1 expressions in peripheral blood mononuclear cells (PBMCs). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific amplification were used to detect PD-1 rs2227982 C>T and PD-L1 rs4143815 C>G.

resultsPD-1 rs2227982 C>T and PD-L1 rs4143815 C>G polymorphisms increased the risk for ovarian cancer. PD-1 rs2227982 C>T was associated with FIGO stage and differentiation grade, while PD-L1 rs4143815 C>G was correlated with histological type and differentiation grade. Besides, PD-1/PD-L1 expressions were positively correlated in PBMCs of patients with ovarian cancer to be associated with differentiation grade. Compared with wild homozygous patients, PD-1/PD-L1 expressions were significantly decreased in PBMCs of ovarian cancer patients carried with the mutant genotypes of rs2227982 C>T and rs4143815 C>G. The PFS and OS in ovarian cancer patients with wild homozygous genotype of rs2227982 C>T and rs4143815 C>G were significantly higher than those with mutant genotypes, which were significantly lower in patients with low expressions of PD-1/PD-L1 than those with high expressions. Univariate COX regression analysis identified FIGO staging, differentiation grade, rs2227982 C>T, rs4143815 C>G and expressions of PD-1/PD-L1 as the prognostic factors, and multivariate COX regression analysis demonstrated that high FIGO stage and low expressions of PD-1/PD-L1 were independent risk factors for the prognosis of ovarian cancer.

conclusionPD-1 rs2227982 C>T and PD-L1 rs4143815 C>G polymorphisms increased the risk of ovarian cancer, leading to a poor prognosis, associated with low expressions of PD-1 and PD-L1. While high PD-1 and PD-L1 expressions are indicators of a favorable prognosis in ovarian cancer.
