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

backgroundAcute appendicitis is the most common cause of the acute abdomen, with an incidence of 1 per 1000 persons per year. It is one of the main differential diagnoses of unclear abdominal conditions.

methodsThis review is based on pertinent publications that were retrieved by a selective search in the PubMed and Cochrane Library databases.

resultsIn addition to the medical history, physical examination and laboratory tests, abdominal ultrasonography should be performed to establish the diagnosis (and sometimes computed tomography [CT] or magnetic resonance imaging [MRI], if ultrasonography is insufficient). Before any treatment is provided, appendicitis is classified as either uncomplicated or complicated. In both types of appendicitis, the decision to treat surgically or conservatively must be based on the overall clinical picture and the patient's risk factors. Appendectomy is the treatment of choice for acute appendicitis in all age groups. In Germany, appendectomy is mainly performed laparoscopically in patients with low morbidity. Uncomplicated appendicitis can, alternatively, be treated conservatively under certain circumstances. A meta-analysis of five randomized, controlled trials has revealed that ca. 37% of adult patients treated conservatively undergo appendectomy within one year. Complicated appendicitis is a serious disease; it can also potentially be treated conservatively (with antibiotics, with or without placement of a drain) as an alternative to surgical treatment.

conclusionConservative treatment is being performed more frequently, but the current state of the evidence does not justify a change of the standard therapy from surgery to conservative treatment.
