Predictors of narrow angle detection rate-a longitudinal study of Massachusetts residents over 1.7 million person years.
Article in Eye (London, England), 2021. 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
BACKGROUND/
objectivesTo determine the predictors of narrow angle detection in a United States population-based cohort. MATERIALS AND
methodsThis was a retrospective cohort study using the Massachusetts All-Payer Claims Database. Demographic information of all patients and eye care provider information during the years 2011-2015 were extracted from Massachusetts All Payers Claims Data. All payers who received eye care during 1/1/2012-12/31/2015 without any previous eye visit during 2011 were included in the analyses. Laser peripheral iridotomy was identified by Current Procedural Terminology code 66761. Narrow angle detection was defined as the diagnosis of narrow angles by diagnosis code followed by a laser peripheral iridotomy procedure. Different predictors of narrow angle detection were evaluated using Kaplan-Meier curves with the log rank and Cox regression modeling.
resultsA total of 1,082,144 patients were included. The hazard ratio of narrow angle detection increased with age compared to the reference group of 0-10 years: 21-30 years of age (hazard ratio = 4.5), 31-40 (10.5), 41-50 (27.9), 51-60 (46.1), 61-70 (68.4), 71-80 (56.8) (all p < 0.0002), was 1.47 times higher in women and 1.85 times higher if evaluated by ophthalmologists compared to optometrists, after controlling for provider × time interaction.
conclusionOlder age and female sex are associated with narrow angles. The rate of narrow angle detection was significantly higher if patients are seen by ophthalmologists compared to optometrists only. Evaluation with an ophthalmologist may be important for patients at high risks for developing primary angle closure glaucoma.
