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

Purpose: To evaluate prediction accuracy using the 4 new-generation formulas (Barrett Universal II (BUII), Emmetropia Verifying Optical 2.0 (EVO), Kane, and Ladas Super Formula (LSF)) and 4 traditional formulas (Haigis, Hoffer Q, Holladay 1, and SRK/T) in eyes undergoing combined phacovitrectomy. Methods: This is a retrospective case series study. In total, 249 eyes of 249 patients undergoing combined phacovitrectomy were enrolled. A single-piece foldable monofocal IOL was implanted in each case. The patients were categorized into three subgroups according to axial length (AL) results. Results: Overall, the 4 new-generation formulas obtained lower mean absolute prediction error (MAE) and median absolute prediction error (MedAE) of 0.42 D to 0.45 D and 0.33 D to 0.36, and higher percentage of prediction error (PE) within ± 0.50 D (65.46%-67.87%). Regarding short eyes, the Haigis formula showed the lowest MedAE of 0.34 D and the highest percentage of PE within ± 0.50 D (68.42%) with no statistical difference, and satisfactory accuracy was achieved using all formulas (all Conclusions: The 4 new-generation formulas showed higher accuracy overall, and higher accuracy was achieved using EVO and BUII formulas in long eyes. All formulas revealed satisfactory accuracy in short eyes. All formulas displayed better accuracy in medium eyes except for Hoffer Q.
