The Prevalence of Nosocomial Infections in the Eastern Mediterranean: Systematic Review and Meta-analysis.
Review in Medical journal of the Islamic Republic of Iran, 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
Background: Evidence-based information on the prevalence of nosocomial infections (NIs) and the determination of influencing factors can play a key role in developing effective infection control activities in healthcare settings, particularly in the East Mediterranean Region (EMR). This study aimed to determine the prevalence of NIs in the EMR. Methods: A comprehensive search of electronic databases-including EMBASE, Google Scholar, Scopus, PubMed, and Web of Science-was done between 2000 and 2021. To estimate the pooled prevalence of NIs in the EMR, a random-effects model was used to measure the effect size with a 95% confidence interval (CI). All analyses were done using a comprehensive meta-analysis. Results: The prevalence of NI in hospital settings was reported to be 13% (95% CI, 0.1-0.16). The highest rate of nosocomial infection was related to wound infection at 39% (95% CI, 0.23-0.58), followed by bloodstream infection at 32% (95% CI, 0.27-0.38). Among the common organisms that infected patients, E. coli was the cause of 16% (95% CI; 0.13-0.2) of NIs followed by Coagulase-negative staphylococci with the prevalence of 15% (95% CI, 0.11-0.19), Acinetobacter at 15% (95% CI, 0.13-0.18) and Staphylococcus at 13%. Study results also revealed a significant relationship between the prevalence of NI, age, and hospital length of stay ( Conclusion: Study results mentioned NI as a widespread challenge in the EMR, which mainly affects elderly patients with complicated clinical symptoms that need long-term hospital stay. To resolve the issue, early detection of infected individuals could improve the quality of response toward the infection.
