Higher Order Aberrations in Patients with Unilateral Nasolacrimal Duct Obstruction.
Article in Korean journal of ophthalmology : KJO, 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
purposeTo compare corneal higher order aberrations (HOAs) in patients with epiphora caused by unilateral primary acquired nasolacrimal duct obstruction (PANDO) and their fellow eyes.
methodsA total of 122 eyes of 61 patients with unilateral PANDO were included. Affected eyes were named as group 1 and contralateral eyes as group 2. The Munk score and fluorescein dye disappearance test (FDDT) were assessed. Corneal topographic and HOAs measurements were taken by Sirius topography.
resultsThere were 47 female and 14 male patients. The mean keratometry was 43.84 ± 1.4 in group 1 and 43.96 ± 1.4 in group 2 (p = 0.73). The mean corneal topographic astigmatism was 0.81 ± 0.7 in group 1 and 0.78 ± 0.5 in group 2 (p = 0.57). The mean coma-like aberration was 0.19 ± 0.2 in group 1 and 0.10 ± 0.1 in group 2 (p = 0.03). The mean spherical-like aberration was 0.16 ± 0.1 in group 1 and 0.11 ± 0.1 in group 2 (p = 0.04). The mean total corneal HOA was 0.30 ± 0.5 in group 1 and 0.23 ± 0.2 in group 2 (p = 0.04). The mean Munk score was 3.47 ± 1.0 in group 1. There was a positive correlation between the Munk score and both coma-like aberration (r = 0.53, p = 0.003) and total corneal HOAs (r = 0.44, p = 0.010). The mean FDDT grade was 2.60 ± 0.1 in group 1. A positive correlation was observed between the FDDT grade and both coma-like aberration (r = 0.48, p = 0.001) and total corneal HOAs (r = 0.33, p = 0.001).
conclusionsEpiphora in patients with PANDO can affect corneal HOAs. As patients' symptoms and tear pooling were increased as corneal HOA levels increased.
