Orbital Doppler ultrasonography evaluation in patients with ankylosing spondylitis: A prospective study.
Article in Northern clinics of Istanbul, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveOur aim in this study is to compare patients with ankylosing spondylitis (AS), a rheumatologic disease that can cause eye involvement and the normal population in terms of orbital Doppler findings, which is an inexpensive and easily applicable method that can be used in early diagnosis and follow-up.
methodsThe study was planned prospectively. The data of patients with AS were compared to those of age- and gender-matched healthy volunteers. A total of 42 participants, 23 (54.8%) males and 19 (45.2%) females, with a mean age of 42.4±12.6 years were included in the study. In addition to demographic information, such as age and gender, the diameter, peak systolic velocity, end-diastolic velocity, mean velocity, resistive index, pulsatility index, and blood flow volumes of the central retinal artery of the left eye were measured using spectral Doppler ultrasonography.
resultsAccording to the comparison of the patients with and without AS according to orbital Doppler ultrasonography findings, the mean velocity, resistive index, and volume measurements of the patients with AS were significantly higher than those without AS (p=0.028, p=0.039, and p=0.038, respectively). However, in the subgroup analysis of the AS group, the Doppler findings did not significantly differ between the patients with and without anterior uveitis.
conclusionIn the patient group with AS, independent of anterior uveitis (AU), there was a difference in Doppler parameters and therefore in ophthalmic vasculature. In patients with AS, orbital vascularity changes can be detected with orbital Doppler US before clinical signs appear.
