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

The role of salivary epidermal growth factor (EGF) in the maintenance of ileal mucosal integrity was studied by evaluating the effects of sialoadenectomy on luminal EGF levels, ileal tissue resistance (Rt), and unidirectional flux of [51Cr]EDTA. Mice in groups 1 (SLX) and 2 (SLX + EGF) were subjected to sialoadenectomy, while mice in groups 3 (Sham) and 4 (Sham + EGF) underwent a sham procedure. All animals received normal diet and water, except that EGF (100 ng/ml) was added to water for SLX + EGF and Sham + EGF mice. At seven days after surgery, luminal EGF levels in gastrointestinal segments and ileal Rt were significantly reduced by sialoadenectomy, which was prevented by EGF supplementation. Unidirectional flux of [51Cr]EDTA was 6- to 22-fold greater in the ileum of sialoadenectomized mice, which was prevented by EGF administration. Results suggest that salivary EGF may be the major source of intestinal EGF, and it may play a role in maintenance of ileal mucosal integrity.
