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
Differences in lenticule shapes may impact on the design of future presbyopic treatments with lenticule surgery. Hence, the objective of this study was to assess the depth of field of eyes after smooth Incision Lenticular Keratomileusis (SILK) surgery for refractive correction of myopia. In this study, patients who underwent SILK surgery were included. At 6 months, all eyes underwent ocular aberrometry with iTrace aberrometer (Tracey Technologies, USA) while fixating at reading targets [distance, intermediate (60 cm), near (40 cm)]. Data from SILK eyes were compared with emmetropic and laser assisted in-situ keratomileusis eyes from an earlier study. A total of 69 eyes were included. At distance and near, eyes from all groups had similar VA clinically. However, emmetropic and SILK eyes had better VA than LASIK eyes at intermediate distance (P < 0.05). Postoperatively, SILK eyes had a greater cylinder at all distances and had greater proportion of eyes with sphere less than - 0.5D at distance than LASIK eyes (P < 0.05). Similarly, SILK eyes had a greater number of eyes with cylinder between - 0.5 to - 1D than LASIK eyes (P < 0.05). Ocular defocus at intermediate and near distance of the SILK eyes were similar to emmetropic eyes but distinct from LASIK eyes (p < 0.05). Overall, induction of higher order aberrations was minimal after SILK. SILK eyes had better VA at intermediate distance compared to LASIK eyes. Nomogram sphere adjustment was adequate for refractive accuracy of SILK surgery and zero-cylinder adjustment provided better intermediate distance vision than the LASIK eyes.
