The effect of COVID-19 imposed lockdown on Italian children with Vernal Keratoconjunctivitis.
Article in The World Allergy Organization journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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: Vernal keratoconjunctivitis (VKC) is a chronic, inflammatory-allergic disease of the cornea and conjunctiva. Environmental factors, such as light exposure, have been supposed to play a role in the pathogenesis of ocular inflammation and in the worsening of VKC. Objective: The aim of this study was to estimate the impact of reduced sunlight exposure in patients with VKC during the imposed lockdown period for the SARS-CoV-2 pandemic emergency. Methods: We retrospectively reviewed data of patients with VKC visited during spring season in 2020 and 2019 at Vernal Keratoconjunctivitis Multidisciplinar Outpatient of our Hospital.Subjective symptoms were evaluated by Visual analogue scale (VAS) and VKC severity was graded by Bonini scale. Quality of life was evaluated by Correlations of Quality of Life in Children with Vernal Keratoconjunctivitis (QUICK) questionnaire. The number of hours of e-learning as well as of hours spent in front of a bright screen (PC, TV, mobile, tablet play station, and so on) was also investigated. Results: Twenty-nine male subjects (mean ± SD age: 8.74 ± 2.40 years) with VKC were included in the study. Most of the patients (17/29) were sensitized individuals.No significant changes in Bonini severity score and in VAS evaluation were observed comparing 2020 to 2019 values. Ten (34.4%) patients did benefit from the reduced sunlight exposure. The increased use of bright screens was associated with worsening of VKC severity. Conclusions: Sunlight exposure plays a role in VKC exacerbation in about one third of patients. The number of hours spent in front of bright screens may influence severity of VKC symptoms.
