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

Necrotizing enterocolitis is the leading cause of morbidity and mortality from gastrointestinal disease in premature infants and is characterized by initial feeding intolerance and abdominal distention followed by the rapid progression to coagulation necrosis of the intestine and death in many cases. Although the risk factors for NEC development remain well accepted, namely premature birth and formula feeding, the underlying mechanisms remain incompletely understood. Current thinking indicates that NEC develops in response to an abnormal interaction between the mucosal immune system of the premature host and an abnormal indigenous microflora, leading to an exaggerated mucosal inflammatory response and impaired mesenteric perfusion. In seeking to understand the molecular and cellular events leading to NEC, various animal models have been developed. However, the large number and variability between the available animal models and the unique characteristics of each has raised important questions regarding the validity of particular models for NEC research. In an attempt to provide some guidance to the growing community of NEC researchers, we now seek to review the key features of the major NEC models that have been developed in mammalian and nonmammalian species and to assess the advantages, disadvantage, challenges and major scientific discoveries yielded by each. A strategy for model validation is proposed, the principal models are compared, and future directions and challenges within the field of NEC research are explored.
