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

Recently, the Sarcocystis parasite in horse and deer meat has been reported to be a causative agent of acute food poisoning, inducing nausea, vomiting and diarrhea. Compared with other causative agents, such as bacteria, viruses and other parasites, in deer meat, the Sarcocystis species parasite, including its stability under various conditions, is poorly understood. In this study, we assessed the viability of Sarcocystis spp. and the activity of their diarrhea toxin (a 15-kDa protein) in deer meat under conditions of freezing, cold storage, pH change and curing. In addition, the heat tolerance was assayed using purified bradyzoites. The results showed that the species lost viability by freezing at -20, -30 and -80°C for <1 hr, heating at 70°C for 1 min, alkaline treatment (pH 10.0) for 4 days and addition of salt at 2.0% for <1 day. Immunoblot assays showed that the diarrhea toxin disappeared together with the loss of viability. However, the parasite survived cooling at 0 and 4°C and acidification (pH 3.0 and 5.0) for more than 7 days with the diarrhea toxin intact. These results provide useful information for developing practical applications for the prevention of food poisoning induced by diarrheal toxin of Sarcocystis spp. in deer meat during cooking and preservation.
