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

Both mechanical and ischemic mechanisms can cause gastrointestinal pain. We investigated whether discomfort and pain caused by bag distension in the esophagus of healthy subjects correlated best with mechanical forces (stress), deformation (strain), or mucosal perfusion. Twenty-nine subjects underwent ramp bag distension using a novel catheter design incorporating high-frequency intraluminal ultrasound, laser Doppler flowmetry, and manometry. Perfusion, pressure, and geometric data were analyzed at visual analog scale (VAS) levels 1-7 in 19 subjects. The circumferential stress increased exponentially as a function of volume, whereas strain showed a linear increase. The perfusion showed a modest decline, on average 15% from baseline to VAS = 7. A significant association was found between the sensory response and stress and strain (P < 0.05). No significant association was found between the sensory response and perfusion. In conclusion, the discomfort and pain response to bag distension in the esophagus is likely to be caused by mechanical rather than ischemic mechanisms.
