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
purposeThe purpose of this study was to determine the accuracy of residual spherical refraction predictability after phacoemulsification (Phaco) intraocular lens (IOL) implant surgery using the SRK/T formula.
methodsA cross-sectional study was performed with a sample size of 112 patients diagnosed with cataracts and indicated for Phaco surgery. This study was conducted in Saigon Can Tho Eye Hospital, Can Tho City, Vietnam, from January 2022 to June 2022. Preoperative data and postoperative data were collected for each case. Residual refraction data were measured using the IOLMaster 500 and Anterion.
resultsThe mean preoperative spherical refraction was 0.04 ± 0.4 diopter. The prediction of residual spherical refraction was -0.11 ± 0.17 diopter (for cases measured by IOLMaster 500: -0.02 ± 0.22 diopter; for cases measured by Anterion: 0.07 ± 0.27 diopter). The mean absolute error of prediction results value in a total of 112 eyes was 0.19 ± 0.21 diopter (for cases measured with the IOLMaster 500: 0.20 ± 0.21 diopter; for cases measured with an Anterion: 0.17 ± 0.26 diopter).
conclusionThe predictive result of the SRK/T formula showed relative and acceptable effectiveness and accuracy in predicting postoperative refraction using the SRK/T formula. The results of this study and those of other studies on the same topic are valuable data to help the ophthalmologist in preoperative consultation with the patient.
