Comparing Lower- and Higher-Order Aberrations: Zywave
Article in Journal of current ophthalmology. 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
Purpose: To assess the agreement between Zywave Methods: In this prospective comparative study, participants aged 20-45 years were examined. Exclusion criteria included previous ocular surgery or trauma, recent contact lens wear, and any ocular or systemic diseases. Each device was operated by an experienced operator who remained blind to the data obtained from the other aberrometer. We compared LOA measurements and the root mean square (RMS) of coma, spherical aberration, and total third- and fourth-order HOAs between the two devices, and the optical zone for measuring HOAs was the same in both the devices. Results: In the study involving 42 eyes of 21 participants (52.4%, female), excellent agreement was observed in LOAs (sphere and cylinder) for both the right and left eyes, with intraclass correlation coefficients of 0.96 and 0.95, respectively, using a 6 mm pupil. In addition, good-to-excellent reliability was reported for the agreement between the two devices in total HOA (t.HOA) and the RMS error of the total aberration, for pupil sizes of 5 mm and 6 mm. However, there was poor agreement between the two devices for third- and fourth-order aberrations in both the pupil sizes. Conclusions: The present study demonstrates agreement between the Zywave
