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
purposeTo evaluate the refractive tolerance in eyes with enhanced monocular intraocular lens (IOL) with a new aspheric design.
methodsThis study included two assessments. Clinical records of consecutive eyes with conventional monofocal IOL (SY60WF, Alcon) were retrospectively reviewed, and changes in uncorrected distance visual acuity (UDVA) with myopic and hyperopic refractive errors were evaluated using segmented regression analysis. Next, in 39 eyes of 39 cataract patients who received an enhanced monofocal IOL (NSP-3, Nidek), UDVA, refractive error, and photopic and mesopic contrast sensitivities were examined at one-three months postoperatively. Changes in the UDVA with refractive error were evaluated in the same manner. With resultant segmented regression lines, ranges of UDVA of 0.20 logMAR or better were obtained as refractive tolerances.
resultsThe clinical records of 717 eyes of 551 patients with SY60WF were analyzed. Segmented regression analysis revealed a breakpoint in emmetropia and UDVA degradation myopically and hyperopically. The refractive tolerance was 2.03 D, while it was 0.73 D on the myopic side. In the prospective study, there was a breakpoint at -1.088 D, where there was a relatively flat slope between the breakpoint and emmetropia, then UDVA steeply degraded. Refractive tolerance on the myopic side was 1.12 D. There was no significant degradation in the photopic/mesopic contrast sensitivity.
conclusionEnhanced monofocal IOLs provided wider myopic refractive tolerance, in which UDVA of 0.2 logMAR or better would be anticipated between emmetropia and myopic error of -1.12 D.
