1 · What the graph read from it

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.

2 · The registry

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

There are close to two billion individuals globally living with presbyopia. In spite of its ubiquitous and progressive nature, there is no widely accepted, formal guideline or consensus statement on the classification of presbyopia by degree of severity. A panel of leading eye care professionals representing both optometrists and ophthalmologists convened virtually to discuss and document their combined assessments from the body of literature and clinical practice expertise in this commentary. In light of emerging therapies, classifying presbyopia by mild, moderate, or advanced severity may help provide consistency of diagnosis among eye care providers and may aid in managing patient expectations with different treatment options.
