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

Hypercontractile esophagus (HE), also known as jackhammer esophagus, is an esophageal motility disorder. Nowadays, high-resolution manometry (HRM) is used to diagnose the disorder. According to the latest iteration of the Chicago classification, HE is present when at least 2 out 10 liquid swallow-induced peristaltic waves have an abnormally high Distal Contractile Integral. In the era of conventional manometry, a similar condition, referred to as nutcracker esophagus, was diagnosed when the peristaltic contractions had an abnormally high mean amplitude. Although the HRM diagnosis of HE is relatively straight-forward, effective management of the disorder is challenging as the correlation with symptoms is variable and treatment effects are dubious. In this mini-review, we discuss the most troublesome uncertainties that still surround HE, in the light of new data on etiology and epidemiology published in this issue of Neurogastroenterology and Motility.
