Korean Version Self-testing Application for Reading Speed.
Article in Korean journal of ophthalmology : KJO, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeThis study introduces a reading chart application for the iPad tablet in the Korean language and investigates the reading speed in a normal-sighted population according to age group.
methodsSixty-three Korean sentences were selected from textbooks for second grade elementary school students. A commonly used typeface in everyday printed material, "BatangChe," was used. Letter size was presented in logarithm of the minimum angle of resolution (logMAR) 0.0 to 1.0 at 0.1 logMAR steps at a reading distance of 40 cm. A third generation retina display iPad was used to present the chart, and the sentences were presented randomly for each size of letter. The subjects repeated the test silently (reading only) and out loud (reading and speaking) to prevent them from skipping reading words. Pilot testing followed in 65 normal vision adults under 60 years of age.
resultsThe mean reading only speed for logMAR 0.5 optotype (point 10) was 121.1 ± 47.2 words per minute (wpm) for people in their 20s (n=21), 116.5 ± 38.3 in their 30s (n=27), 93.8 ± 12.6 in their 40s (n=9), and 56.5 ± 42.7 (n=8) in their 50s. There was a significant correlation between age and reading and speaking speed (r=-0.48, p<0.001). The mean reading only speed for logMAR 0.5 optotype (point 10) was 202.3 ± 88.4 wpm and the mean reading and speaking speed was 129.7 ± 25.9 wpm, with significantly different (p<0.001).
conclusionsThis Korean reading chart application could present a new standard when checking reading speed according to age groups.
