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

Individuals with particular genetic backgrounds develop immune responses to wheat proteins and become 'gluten-sensitised'. Mucosal pathology arises through activated mucosal T lymphocytes, resulting in a graded, adverse reaction between particular genes and wheat proteins. Given these varied influences, the Marsh Classification broadly itemises those stages through which a normal mucosa (Marsh 0) evolves in becoming 'flat' (Marsh I, II, III). Recently, Oberhuber and colleagues suggested that Marsh III lesions required subdividing into a, b, c categories. We critically examined these subdivisions by means of correlative light and scanning electron microscopy (SEM). Our results demonstrate that Oberhuber's classification is untenable. In our view deriving from our observations, the artificial subdivisions proposed by those authors actually reflect misinterpretations of the true architectural contours of flat mucosae. Although these workers refer to "villous projections", SEM demonstrates that no such structures are present on flat - or immediately recovering - mucosae. Our data revealed on the surfaces of flat (Marsh III) mucosae, large open "basins", surrounded by raised collars - the latter, when viewed in histological section, being easily misconstrued as "villi". It seems that with subsequent upward growth, these collars coalesce into low ridges, thence becoming broader and higher convolutions. It is noticeable that there are more open spaces on the surfaces of flat mucosae than was appreciated hitherto. We conclude that Oberhuber's revisions of Marsh III into three subcategories (a, b, c), are misinterpretations of the histological appearances of flattened mucosae. Therefore, histopathologists when classifying celiac mucosae, since they add nothing either of diagnostic, nor prognostic, value should resist these subcategories.
