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

backgroundBoth influenza A infection (IAV) and type I hypersensitivity mechanisms have been independently linked to acute appendicitis. Particularly the expression of type I hypersensitivity associated with cytokine interleukin (IL) 13 has been shown to be of significance in both, appendicitis and influenza infection. The aim of the current study was to analyze possible associations of respective gene expressions at the level of mathematical correlations.

methodsWe analyzed messenger RNA (mRNA) gene expressions of IAV-associated markers, hypersensitivity type I-related cytokines and inflammatory markers IL-17A and c-reactive protein (CRP) in peripheral blood mononuclear cells from 29 children aged 7-17 years, who were operated for histologically confirmed appendicitis at Charité-Universitätsmedizin Berlin between April and August 2019. Statistical relationships between gene expressions were investigated using Spearman's correlation analysis, with a correlation coefficient r ≥ 0.5 or r ≤ - 0.5 representing high, and r ≥ 0.7 or r ≤ - 0.7 very high correlations. Statistical significance was assumed at P < 0.01.

resultsA total of 29 patients were involved in this study. Particularly the expression of IL-13 showed highly significant negative correlations with that of IAV-specific antiviral response genes, ranging from - 0.89 (P < 0.0001) to - 0.49 (P = 0.006). A strong inflammatory background was demonstrated by very high correlations of IL-13 with CRP (r = 0.91, P < 0.0001) and IL-17A (r = 0.82, P < 0.0001).

conclusionThese findings suggest a connection between IAV infection and acute appendicitis in children, implicating sequential immune responses, including hypersensitivity type I mechanisms, in appendicitis pathophysiology.
