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

objectiveTrefoil factor (TFF) peptides are expressed in gastric tissues, where they are part of the epithelial defences. To complement previous in vitro work, the goal of the present study was to examine directly if TFF2 was essential for gastric restitution in vivo during the recovery from microscopic damage.

designTFF2 mutant (KO) mice were examined to study the epithelial repair process in vivo after laser-induced photodamage (LPD). Using two-photon laser energy absorption (710 nm), LPD was imposed on an approximately 3-5 cell region of surface epithelium in anaesthetised mouse stomach. Responses to damage were evaluated during confocal time-lapse microscopy; including area of damage and the extracellular pH adjacent to the damaged surface (Cl-NERF pH sensor).

resultsIn control (TFF2+/+ and TFF2+/-) mice, damaged cells were exfoliated and the damaged epithelium was repaired by indomethacin. The resting surface pH was similar between control and TFF2-KO animals, but the post-LPD alkalisation of surface pH observed in control mice (pH 0.3 + or - 0.05, n=21) was attenuated in the TFF2-KO stomach (pH -0.08 + or - 0.09, n=18). Recobinant rat TFF3 partially rescued the attenuated surface pH change in TFF2-KO stomach, in the presence or absence of indomethacin.

conclusionsIn the gastric epithelium in vivo, TFFs promote epithelial restitution via a mechanism that does not require cyclooxygenase activation. A novel role for TFFs to affect gastric surface pH is observed.
