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 prevalence of Helicobacter pylori (H. pylori) infection increases with age. However, the relationship between H. pylori infection and anemia in the elderly population remains to be identified. The aim of this study is to explore whether H. pylori infection is associated with anemia in a male elderly cohort.

methodsA cross-sectional study was designed using data collected from asymptomatic male senior citizens (≥ 65 years old) who received an assessment of their health status at the General Hospital of Chinese PLA from January 2015 to December 2015. H. pylori infection was confirmed by the

resultsData from 646 subjects were analyzed. The mean age of the study cohort was 79.4 ± 8.9 years. The overall prevalence of H. pylori infection was 35.3%. The prevalence of anemia in the H. pylori positive group was higher than that in the negative group (5.3% vs. 2.2%, P = .033). Among the patients who had higher CCI scores (> 2), the prevalence of anemia in the H. pylori positive and negative groups were 10.3 and 1.4%, respectively (P = .009). Compared to the H. pylori negative group, the odds ratio for anemia of the H. pylori positive group was 2.53 (P = .033). No correlation between H. pylori infection and serum iron and ferritin levels was found. The mean corpuscular volume of the H. pylori positive and negative group was 91.17 ± 3.94 fl and 91.17 ± 4.09 fl (mean ± SD), respectively (P = .986). The CRP level in the H. pylori positive group was higher than that in the H. pylori negative group (Median: 0.17 mg/dL vs. 0.10 mg/dL, P < .001).

conclusionH. pylori infection seems to be associated with normocytic and normochromic anemia in elderly males, especially in those with more comorbidities. Further clinical studies are needed to verify the association.
