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

This study aims to review the global mortality secondary to laryngeal edema in patients diagnosed with hereditary angioedema and their relatives over the years, as well as to describe epidemiological and clinical findings associated with this outcome. An extensive search of the literature was made in PubMed, Scopus, and Embase to identify mortality rates secondary to laryngeal edema in patients with hereditary angioedema. The search was carried out in September of 2020 and in April of 2021, and keywords based on the MeSH terms were searched in three databases. The filter of language was used for finding only articles in English, and there was no limit to the year of publication. A total of twenty-three articles fulfilled the inclusion criteria for review and data extraction. The analyzed studies included 3292 patients and 411 deaths from asphyxia due to laryngeal edema. One hundred and three deaths in close relatives were described as secondary to the same cause. The main findings were summarized in tables: year and place of publication, the number of patients and deaths from laryngeal edema, patients previously diagnosed, and death age. Death rates from laryngeal edema had an average of one death for every 20 patients. Eight studies reported deaths in relatives. For every 7.4 patients in these studies, one relative died. The percentage among deaths in general associated with laryngeal edema was evaluated in three studies (32.7%, 44.4%, and 56%). The high frequency of this outcome suggests that deaths still occur, and improvement of hereditary angioedema treatment still needs to be met.
