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

The objective of this study was to investigate the frequency and functionality of DCs and its associated stimulatory and inhibitory markers in the pathogenesis of PV Active PV patients (n = 30) having both skin and oral lesions, and 30 healthy controls were recruited in the study. The frequency of DCs was determined by flow cytometry followed by the primary culture by using recombinant IL-4 (250 IU/ml) and GM-CSF (600 IU/ml). The culture supernatant was used for ELISA. RNA was isolated from sorted DCs and used for the mRNA expression of DC-associated stimulatory (CD40 and CD80) and inhibitory (PSGL1 and ILT3) markers. Tissue localization of Langerhans cells was done by immunohistochemistry. In this study, altered frequency of myeloid DC (mDC) and plasmacytoid DC (pDC) was seen in the circulation of PV patients. The primary culture of patient-derived DCs showed anomalous cytokine profiling. In the culture supernatant of DCs, elevated levels of TNF-ɑ and IL-12 were detected in PV patients. Meanwhile, reverse trend was found in the case of IFN-ɑ and IL-10 cytokine levels. Similarly, a discrepancy in the expression of DC-associated stimulatory (CD40 and CD80) and inhibitory (PSGL1 and ILT3) markers suggested their possible involvement in the immunopathogenesis of PV. An elevated number of tissue localizing Langerhans cells was also observed in the perilesional skin. This study indicates the distorted frequency and functionality of DCs in the immunopathogenesis of PV. Targeting these functional markers in the future may generate novel therapeutic options for better management of PV.
