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

purposeThe aim of this study was to explore the status of quality of life between the ages 40-59 in relation to presbyopia and dry eye.

methodsNear add power and preferred contact lens power were examined in 219 participants at three clinics. 2000 participants completed a web-based survey on presbyopic symptoms, symptomatic dry eye, sleep quality, and subjective happiness.

resultsMean preferred corrected visual acuity was less than 20/20 in women (vs men, P<0.01) who were more often prescribed under-corrected contact lenses, whereas men preferred full correction. According to the annual progression rate of near add power in men (0.1468D/year), the estimated difference in presbyopia progression between men and women was 0.75 years in the right eye, and 1.69 years in the left eye, implying men might suffer presbyopia earlier than women due to higher myopic power of daily use contact lenses. The web-based survey revealed that men reported lower subjective happiness than women (P<0.001) and earlier onset of presbyopic symptoms by 1.1-1.7 years (P<0.05). Men received their first reading glasses 0.8 years earlier than women (P = 0.066). Multiple regression analysis demonstrated that awareness of presbyopic symptoms, visual burden, and dry eyes were significantly correlated with poor sleep quality and subjective happiness.

conclusionPresbyopia and dry eye were significantly associated with sleep quality and subjective happiness in middle-adulthood.
