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

This paper aimed at investigating the alterations in interstitial cells of Cajal (ICCs) in the murine small intestine from 0-day to 56-day post-partum (P0-P56) by immunohistochemistry. The Kit+ ICCs, which were situated around myenteric nerve plexus (ICC-MY) formed a loose cellular network at P0 which changed into an intact one before P32. The density of ICC-MY increased from P0 to P12, and then decreased until P32. In contrast, the estimated total amount increased more than 15-fold at P32 than that at P0. Some Kit+/BrdU+ cells were observed at 24 h after one BrdU injection to the different-aged mice, and the number decreased from P2 to P24 and vanished at P32. Actually a few Kit+/BrdU+ cells can be observed at 1 h after one BrdU injection at P10, and the amount doubled at 24 h along with paired Kit+/BrdU+ cells. A number of BrdU+ ICCs were also labeled with CD34, CD44 and insulin-like growth factor I receptor. About 65% ICCs were BrdU+ at P32 after daily BrdU injection from P0. Our results indicate that an age-dependent proliferation is involved in the postnatal development of ICC-MY which increase greatly in cell numbers and proliferative ICCs may originate from ICCs progenitor cells.
