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

purposeSTING (stimulator of interferon genes) is involved in viral and bacterial defense through interferon pathway and innate immunity. Increased susceptibility to infection is a common manifestation of multiple myeloma (MM). Thus, we aimed to explore the clinical significance and possible mechanism of STING in MM. MATERIALS AND

methodsImmunohistochemistry and qPCR were used to detect STING expression in the bone marrow of MM patients, and flow cytometry was used to detect the amount of intracellular STING. All data were analyzed with clinical characteristics.

resultsSTING expression was remarkably reduced in MM tissues compared to normal tissues and was not associated with stage. Multivariate analysis identified STING as an independent prognostic factor in MM patients (P = 0.001). In the bortezomib-containing regimens, patients with low STING expression were more difficult to achieve remission. A model incorporating STING and m-SMART significantly improved the predictive accuracy of overall survival in bortezomib regimens (AUC, 0.511 to 0.630, P = 0.044). Bortezomib efficacy has been reported to correlate with activated immunity, but the low expression group manifested as immune apathy. Although baseline characteristics showed intergroup differences in infection, the low expression group had an increased proportion of bacterial infections (1.7-fold) and a prolonged duration of antibiotic/antifungal medication (3.55 additional days); these patients were accompanied by a decreased neutrophil-to-lymphocyte ratio (NLR) and rarely activated neutrophils and leukocytes. The intracellular STING ratio was also defective in neutrophil-dominated leukocytes.

conclusionOur study revealed that STING had a strong association with bortezomib and could serve as a potential target for immunotherapy in multiple myeloma.
