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

purposeTo investigate how the configuration of residual astigmatism, defined by the location of Sturm's conoid, affects visual acuity loss in pseudophakic eyes, and to compare scalar and vector-based defocus equivalents as predictors.

methodsThis retrospective study included 75 pseudophakic eyes post cataract surgery with aspheric or toric monofocal intraocular lenses. Manifest refraction was measured 4-8 weeks postoperatively. Eyes with residual refractive cylinder between 0.50 and 1.25 D and best corrected distance visual acuity (CDVA) ≤ 0.20 logMAR were included. Visual acuity loss (VAL) was defined as uncorrected distance visual acuity (UDVA) minus CDVA. The defocus equivalent (DEQ) was calculated using two methods. DEQ

resultsVAL showed a robust linear relationship with DEQ

conclusionThe impact on UDVA depends not only on DEQ, but also on residual astigmatism type. DEQ
