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

The present controlled cross-sectional study aimed to assess relative and absolute lymphocytosis and lymphopenia induced by imported infectious diseases (IDs) seen among patients consulting the Division of Infectious Diseases and Tropical Medicine, Medical Center of the University of Munich (1999-2014) after being in the tropics and subtropics. The analysis investigated data sets from 17,229 diseased German travelers returning from Latin America (3,238), Africa (5,467), and Asia (8,524), and from 1,774 healthy controls who had not recently traveled. Among the cases, the proportion of those with relative lymphopenia (10.5%) and absolute lymphopenia (8.0%) was significantly higher than among controls (3.2% and 3.6%, respectively), whereas relative lymphocytosis was significantly lower among cases (6.1%) than among controls (8.0%). The study identified IDs with significantly larger proportions of relative lymphocytosis (cytomegalovirus [CMV] infection [56%], infectious mononucleosis [51%], and dengue fever [11%]); absolute lymphocytosis (infectious mononucleosis [70%] and CMV infection [63%]); relative lymphopenia (streptococcal pharyngitis [56%], malaria [34%], Campylobacter infection [19%], salmonellosis [18%], and shigellosis [17%]); and of absolute lymphopenia (human immunodeficiency virus infection [53%], malaria [45%], dengue fever [40%], salmonellosis [16%], and Campylobacter infection [11%]). This study demonstrates that relative and absolute lymphocytosis and lymphopenia are useful laboratory findings for travelers returning from the tropics and subtropics, as they are typically caused by imported viral, bacterial, and protozoan IDs.
