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

backgroundSkin tags (ST) are common benign tumors of the skin but their etiopathogenesis is not well understood. STs arise in sites subjected to trauma. It was proved that mast cells are recruited to sites of skin trauma and increase their tumor necrosis factor-α (TNF-α) content.

aimSTs are linked to obesity and frictional sites, but this has not been studied at the molecular level. We hypothesized that mast cells, TNF-α and its family member, TNF-related apoptosis-inducing ligand (TRAIL) might play a role in the pathogenesis of STs as a response to trauma. MATERIALS AND

methodsA study was done on 15 patients with STs. Two STs and a snip of normal skin were obtained in each subject. We counted the mast cells after Toluidine blue staining. Enzyme-linked immunosorbant assay was used to measure TNF-α level while reverse transcriptase polymerase chain reaction was used to evaluate the level of TRAIL mRNA expression.

resultsMast cell count in all STs was significantly higher than that in control (P=0.0355). There was a highly significant increase in the level of TNF-α in all STs as compared to its level in controls (P<0.0001). Expression of TRAIL mRNA was significantly higher in STs as compared to its expression in controls (P<0.0001).

conclusionOur study suggests that mast cells, TNF-α and TRAIL may play a role in the pathogenesis of STs.
