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

Background: Polymicrobial keratitis is an uncommon but vision-threatening condition, particularly when it involves protozoal and bacterial pathogens. Healthcare workers may be at increased risk due to occupational exposure to hospital-associated microorganisms. Case Presentation: We report a case of severe polymicrobial keratitis in a 40-year-old contact lens-wearing nurse who developed acute keratitis following inadvertent ocular exposure to nasogastric secretions while caring for a critically ill child. Contact lens culture and in vivo confocal microscopy identified Conclusion: This case represents a rare example of occupationally acquired polymicrobial keratitis involving Acanthamoeba and multiple healthcare-associated bacteria. It highlights the potential for gastrointestinal and hospital flora to cause severe ocular infection in contact lens users and underscores the need for heightened infection-control awareness among healthcare workers.
