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

backgroundThe methods for assessing colonic transit in patients with functional constipation include the radiological method and Tc-99m scintigraphic method. This study aims to validate the practicality and accuracy of the Tc-99m scintigraphic method in evaluating colon transit, while also exploring the significance of the geometric center (GC).

methodsOur study is a single-center, retrospective analysis. We examined the medical records of 47 patients, who underwent colonic transit by the Tc-99m scintigraphic method and the radiological method for investigation of chronic constipation. Geometric center (GC) and transmit index (TI) were calculated respectively in these two methods. The patients were divided into four types of constipation: normal transit constipation (NTC), slow transit constipation (STC), defecatory disorders (DD) and STC combined with DD.

resultsThe results of the Tc-99m scintigraphic method and radiological method were consistent in the diagnosis of slow colon transmission (Kappa value = 0.718, P < 0.001). TI and 48-h GC were positively correlated (r = 0.657, p = 0.001). Patients with DD exhibited higher 24-h GC and 48-h GC values compared to those with STC.

conclusionTc-99m scintigraphic method can be used to evaluate colonic transit in patients with constipation, and GC values may be used to distinguish the types of constipation.
