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

purposeAppendicoliths are one of the important causes of acute appendicitis. Currently, there is no consensus on the relationship between appendicoliths and complicated appendicitis, and opinions on the treatment of appendicolith-associated appendicitis vary. This study aims to determine the significance of appendicolith in acute complicated appendicitis and to assess the characteristics of appendicoliths and Computed tomography (CT) features associated with complicated appendicitis.

methodsA retrospective analysis was conducted on patients who underwent surgical treatment for acute appendicitis at the affiliated hospital of Qingdao University from January 2016 to October 2023. Acute appendicitis was classified into two groups with and without appendicolith based on CT findings, intraoperative observations, and postoperative pathology. The clinical data of the two groups were analyzed and compared. Further subgroup analysis was performed within the appendicolith group based on pathological findings, comparing the location, size, and number of appendicoliths, as well as the length, diameter, and CT features of the appendix.

resultsAmong 331 patients with acute appendicitis, 179 had appendicolith, of which 106 were complicated appendicitis and 73 were uncomplicated appendicitis. Among 152 patients without appendicolith, 44 had complicated appendicitis and 108 had uncomplicated appendicitis. appendicoliths were independently associated with complicated appendicitis (OR = 1.88, 95% CI: 1.04-3.40, p = 0.036). In patients with appendicolith appendicitis, three factors were independently associated with complicated appendicitis: appendiceal diameter (OR = 1.20; 95% CI: 1.03-1.40), moderate-severe fat stranding (OR = 17.61; 95% CI: 3.19-97.33), and periappendiceal air (OR = 9.78; 95% CI: 1.17-81.46).

conclusionAppendiceal appendicoliths are closely related to acute complicated appendicitis. The diameter of the appendix and moderate-severe fat stranding, periappendiceal air on CT are significant indicators for identifying complicated appendicitis in acute appendicitis with appendicolith.
