Monocular reading performance measured by MNREAD-P acuity chart in normo-readers schoolchildren.
Article in Scientific reports, 2025. 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
This study aimed to determine and establish values for reading performance in normo-readers schoolchildren. Literate students aged 8 to 18 years old without visual impairments were recruited. The MNREAD-P chart was used to assess monocular reading acuity (RA in logMAR), critical print size (CPS in logMAR), and maximum reading speed (MRS in words per minute - wpm). Participants were grouped into three education levels: Elementary School I (3rd to 5th grade), Elementary School II (6 to 9th), and High School (10 to 12th). Lower and upper normal limits were determined using a 95% confidence interval around the mean. The association of RA, MRS, and CPS with sex, heterophoria, and education level was analyzed with a significance level of p ≤ 0.05. The final sample included 184 eyes from 92 participants (65% female) with a mean age of 12.8 ± 2.9 years. The normative lower limits were: (a) RA of 0.1 logMAR for Elementary I and II and 0.0 logMAR for High School; (b) CPS of 0.3 logMAR for all education levels; (c) MSR of 116 wpm for Elementary I, 159 wpm for Elementary II and 192 wpm for High School. Higher education level was significantly associated with improvement in RA (p = 0.017) and MRS (p < 0.001).
