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

backgroundPlacental extract (PE) is rich in peptides, amino acids, nucleic acids, vitamins, and minerals. Although PE is used for skin care and as a health food, it is also considered effective in the treatment of various diseases. Mast cells play an essential role in allergic diseases by secreting various inflammatory mediators, such as histamine, leukotrienes, and prostaglandins. PE has inhibitory effects on mast cell activation; however, the molecular mechanisms underlying these inhibitory effects remain unclear. The aim of this study was to investigate the mechanisms underlying the inhibitory effects of PE on mast cell activation. METHODS AND

resultsIn this study, we used rat basophilic leukemia (RBL-2H3) cells as a mast cell model. We showed that short-term treatment with porcine PE (PPE) inhibited degranulation in a dose-dependent manner and demonstrated that this inhibitory effect was because of the blockade of extracellular Ca

conclusionsOur results indicate that low-molecular-weight components of PPE inhibit mast cell degranulation by blocking Ca
