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

objectivesEndometrial cancer (EC) is the most common cancer of the female genital tract. Egypt showed a significant increase in incidence lately of which 25% were premenopausal. Advanced or recurrent disease are mostly unresectable and the traditional adjuvant therapy give modest results with devastating side effects. Late discoveries of immune checkpoint inhibitors have produced promising results. Programmed cell death 1 (PD1) is an immune inhibiting receptor on surface of lymphocytes, which plays critical roles in maintaining immunological self-tolerance. There are two ligands for this receptor, PDL1 and PDL2. PD-L1 is expressed on tumor cells; attaches to PD1, allowing tumor cells to escape from the host immune response. Its prognostic significance in various tumors is controversial and its significance in ECs has just begun to be investigated. Therefore, we investigated the relationship between PDL1 expression and different clinicopathologic parameters in EC cases and its correlation with CD4 and CD8 immune cells, in order to identify the predictive biomarkers for the outcome by immune therapy.

methodsHundred, paraffin tissue blocks of EC cases were collected and stained with antibodies against PDL1,CD4 and CD8.

resultsPDL1 was positive in 67% of cases in tumor cells and in 61% of cases in immune cells. CD4 and CD8 were expressed in 79% of cases. Statistically significant correlations were observed between PDL1 expression and patients mean age, LVSI, TILS score and CD4+/CD8+ expression.

conclusionThose variables can stratify candidates who can benefit most from immunotherapy, or can be chosen for further high cost molecular investigations application.
