Systemic comorbidities, seasonal onset, and antihypertensive medication use in primary angle-closure disease subtypes.
Article in International journal of ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo investigate clinical characteristics, comorbidities, seasonal onset, and antihypertensive medication use among acute primary angle-closure (APAC), chronic primary angle-closure glaucoma (CPACG), and primary angle-closure suspect (PACS) patients.
methodsA retrospective cross-sectional study of 484 Chinese patients was conducted. Baseline demographics, hypertension and diabetes prevalence, antihypertensive medication use, and seasonal onset patterns were compared across primary angle-closure disease (PACD) subtypes. Seasonal variation was assessed using the von Mises distribution, with subgroup analyses stratified by systemic conditions and medication use.
resultsCPACG patients were older (median 71
conclusionVascular and metabolic comorbidities are more prevalent in CPACG than APAC, suggesting their role in CPACG pathogenesis. The early-summer peak in disease onset points to possible environmental triggers. Seasonal variation in APAC onset appears to be influenced by systemic vascular conditions and antihypertensive medication use, supporting a multifactorial interaction between environmental, systemic, and pharmacologic factors in APAC.
