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

objectivesTo determine whether the combination of resolvin E1 (RvE1) and lipoxin A4 (LXA4) could promote resolution of pulpitis and to investigate the mechanism. MATERIALS AND

methodsPreliminary screening was first conducted in four specialized pro-resolving mediators (SPMs). Real-time quantitative polymerase chain reaction, western blotting, enzyme-linked immunosorbent assay and double-immunofluorescence labelling were employed to assess the expression of RelA, SIRT1, SIRT6, SIRT7 and pro-inflammatory factors. Dental pulp fibroblasts (DPFs) were transfected with siRNA to assess the biological role of SIRT7. A pulpitis model was utilized to evaluate the in vivo curative effect.

resultsPreliminary results showed that RvE1 and LXA4 reduced the expression of RelA more markedly than other two SPMs. Both RvE1 and LXA4 treatment downregulated nuclear factor kappa B (NF-κB) activation and increased the expression of SIRT1, SIRT6 and SIRT7, more so in combination than alone. Double-immunofluorescence labelling showed that SIRT7 co-localized with p-p65 and Ac-p65 in the nucleus. Inhibiting ChemR23 and ALX reversed the expression of RelA mRNA, p-p65 and Ac-p65 proteins, pro-inflammatory factors, SIRT1, SIRT6 and SIRT7. Silencing SIRT7 significantly increased p-p65 and Ac-p65 protein levels and decreased SIRT1 and SIRT6 expression. In vivo experiments showed that combined administration of RvE1 and LXA4 promoted pulpitis markedly to resolution.

conclusionsCombination of RvE1 and LXA4 effectively inhibited NF-κB activation by upregulating SIRT7 expression in DPFs, leading to reduced production of pro-inflammatory factors and promotion of pulpitis resolution.
