New-onset conjunctivitis 3.5 years post SARS-CoV-2 infection in an inner-city population in the Bronx.
Article in BMJ open ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundA few studies have reported conjunctivitis is a complication associated with acute COVID-19. It is unknown whether SARS-CoV-2 infection increases the risk of conjunctivitis post-COVID-19 long term.
objectivesThis study investigated the incidence of new-onset conjunctivitis 3.5 years post SARS-CoV-2 infection and compared it with patients without SARS-CoV-2 infection.
methodsThis retrospective study consisted of 67 702 patients who tested positive for COVID-19 (defined by a positive PCR test), and 1 391 135 COVID-19-negative patients with no prior records of conjunctivitis in the Montefiore Health System from 11 March 2020 to 31 December 2022. The study included adult patients re-presenting to our centre with conjunctivitis. Outcome was new conjunctivitis between 14 days and 3.5 years post index date. Analysis was performed with unmatched and matched cohorts. Matching was done for age, sex, race and ethnicity. Cumulative incidence and hazard ratio (HR) with and without adjustment for competitive risks were analysed.
resultsThere were 1154 (2.27%) individuals with COVID-19 and contemporary 13 899 (1.57%) controls who developed new conjunctivitis. COVID-19-positive patients had a significantly higher risk of developing new incident conjunctivitis (unmatched cohort adjusted HR 1.11 (95% CI 1.04 to 1.17), matched cohort adjusted HR 1.10 (95% CI 1.02 to 1.16)) compared with COVID-19-negative patients.
conclusionsCOVID-19-positive patients had significantly higher risk of developing new conjunctivitis compared with contemporary COVID-19-negative controls. Identifying risk factors for developing new-onset conjunctivitis may draw clinical attention for careful follow-up in at-risk individuals for ocular infections.
