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
Purpose: To determine if preoperative ocular higher order aberrations (HOAs) were associated with changes in uncorrected distance (UCDVA), intermediate (UCIVA), near (UCNVA), corrected distance at reduced contrast (CDVA 10% and 25%) logMAR acuities after PCIOL or aspheric IOL implantation. Patients and Methods: Records of patients implanted with AcrySof IQ PanOptix (group I, n = 30), TECNIS Symfony (group II, n = 35), TECNIS bifocal (group III, n = 34), or TECNIS monofocal (group IV, n = 32) were reviewed where UCDVA, reduced contrast CDVA (logMAR chart at 6 m), UCIVA and UCNVA (at 80 cm and 40 cm) assessed under photopic conditions (∼85 cd/m Results: Data from one eye/case were included for analysis. The chief findings were: (i) Median UCDVA, UCIVA and UCNVA values improved but CDVA (10% and 25%) remained unchanged in groups I-III. Median UCDVA, CDVA (10% and 25%) improved but UCIVA and UCNVA values remained unchanged in group IV. (ii) Mean spherical aberration (5mm pupil) and total root mean square HOA values (for 3 and 5mm pupil sizes) reduced in all 4 groups (ANOVA, p < 0.001). Mean trefoil and coma values did not change significantly. (iii) There were significant correlations between changes (Δ) in uncorrected acuities, CDVA (10% and 25%) and specific preop HOA values. The limits of agreement in the various models describing these associations were ≤0.2 units of logMAR acuity in groups II for ΔUCIVA and ΔCDVA (10% and 25%), III for ΔUCNVA and ΔCDVA (10% and 25%), IV for ΔUCIVA and ΔCDVA (10% and 25%). Conclusion: Preoperative HOA measurements showed statistically significant though modest associations with changes in uncorrected visual acuities. In some instances, the estimated change improved by including information regarding preoperative refractive error. Validation in larger cohorts is required before clinical implementation.
