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

Basic control theory equations are developed showing classical exponential system response of refraction vs. time R(t), with a characteristic system time constant, in response to a negative (-) step change of near work environmental conditions. Statistical analysis of retrospective data from 226 subjects is presented. It is shown that reasonable significance levels p < 0.001 can be obtained from relatively small sample sizes, over short time intervals. Details from preliminary experimental design using reading glasses at the U.S. Naval Academy at Annapolis are discussed. The conclusion is that positive (+) Add lenses, used as reading glasses during study, can prevent the development of myopia of college students in pilot training.
