Choroidal structural changes in airline pilots and cabin crew.
Article in International ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeTo analyze the differences in terms of choroidal vascularity index (CVI) and choroidal thickness (CT) between the airline pilots-cabin crew and the normal population.
methodsIn this prospective study, 50 airline pilots-cabin crew (study group) and 50 healthy individuals (control group) were included for comparison. For each participant, one eye, the eye with the higher OCT scan score index, was enrolled. Subfoveal CT and CVI were measured using a spectral-domain optical coherence tomography system with enhanced depth imaging.
resultsThere were no significant differences in terms of age and sex between the study and control groups. The mean CT was 368.5 ± 79.6 in the control group vs. 424.9 ± 80.7 in the study group (p = 0.001). CT was significantly thicker in the study group. The mean CVI was 64.3 ± 1.5 in the control group and 66 ± 3.1 in the study group (p = 0.5). There was no significant correlation between the study and control groups in terms of CVI.
conclusionAirline pilots-cabin crew had thicker CT, but there were no differences in CVI when they were compared with healthy subjects. The effect of unique occupational exposures of airline pilots-cabin crew to the pathophysiology of choroidal structural alterations needs further investigation.
