Prevalence of Bartonella spp. infections in Iran: a systematic review and meta-analysis.
Synthesis in Archives of Razi Institute, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Despite the public health importance of Bartonella infections, its epidemiology is under-studied, particularly in Iran. The objective of this systematic review and meta-analysis was to determine the pooled prevalence of Bartonella infections in humans, domestic and wild animals, and invertebrates in Iran, respectively. PubMed, Scopus, Web of Science, Google Scholar, Scientific Information Database (SID), MagIran, and IranDoc databases were searched. Title and abstract screening was done by two independent reviewers based on the eligibility criteria. The eligibility criteria were cross-sectional studies investigating the prevalence of Bartonella infections in humans, pets, farm animals, and parasites in Iran. A random-effects model with Freeman-Tukey Double Arcsine transformation was used for data synthesis. Subgroup analysis was done based on the host species. A total number of 220 results were identified by the search, among which 93 were removed as duplicates. Of the 127 remaining results, 19 studies were included. The molecular prevalence of Bartonella spp. infections was 4% with the highest values observed in rats (17%), dogs (10%) and cats (10%), respectively. The seroprevalence of Bartonella spp. among cat owners and hospital patients in Tehran was 18% and 5%, respectively. Also, the seroprevalence of Bartonella spp. among dogs in Hamadan was estimated to be 74.24%. Based on culture methods, in one study among cats in Shahrekord, 12.5% of blood samples were positive. Based on the findings of the current study, the molecular prevalence of Bartonella spp. in Iran was higher in rats, dogs, and cats. However, more investigations, particularly in other hosts, are recommended.
