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

purposeColonic manometry (CM) can be of additive value in the diagnostic workup of colonic motility in chronic constipated patients. However, it is claimed that colonic motor disturbances occur in normal-transit constipation (NTC) and slow-transit (STC) constipation, as measured using a radio-opaque marker study, and therefore, the relationship between colonic motor disturbances on CM and colonic transit time (CTT) remains unclear. Our aim was to compare results from colonic marker study with the outcome of CM in patients with treatment-refractory chronic constipation (CC).

methodEighty-seven CC patients and 12 healthy volunteers, undergoing both a CTT study and a 24-h CM in a Dutch tertiary referral center, were included. CTT was measured using radio-opaque markers (X-ray at day 4 after ingestion of 20 markers at day 0). CM was performed using a catheter with 6 solid-state pressure sensors, endoscopically clipped to the mucosa in the right colon. CM was defined as normal when at least three high-amplitude propagating contractions (HAPCs), i.e., propagating waves with amplitude ≥ 80 mmHg over at least three sensors, were identified.

resultsIn total, 70 patients showed STC on CTT, of which 21 (30%) showed normal CM. All 17 NTC patients and healthy volunteers showed normal CM. The negative predictive value of CTT for normal CM was 100%.

conclusionColonic manometry should be considered in therapy-refractory STC patients in order to further delineate colonic motility. However, in this exploratory study, for patients presenting with NTC on a radio-opaque marker study, colonic manometry does not appear to have added value.
