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 develop and test a formula for contact lens calculation in aphakic infants. This formula, termed the "aphakic Contact Lens" (aCL) formula, utilizes preoperative axial length and keratometry data.
methodsThis retrospective, consecutive, two-center study used data derived from a development cohort (Freiburg, Germany) to create and optimize the aCL formula in aphakic eyes. A separate validation cohort (Frankfurt, Germany) was used to validate its predictive performance. The accuracy of the aCL formula was compared against: retinoscopy, a previously reported formula (Trivedi and Wilson, TW), and the use of a + 32.0 diopter (D) CL. Performance was evaluated using the prediction error (PE), absolute prediction error (AE) and the number of eyes within a certain range from retinoscopy (± 0.5D, ± 1.0D, ± 2.0D).
resultsThe aCL formula demonstrated comparable absolute prediction errors to retinoscopy (median AE 0.53D vs. 0.69D) and outperforms the TW formula or + 32D CL (median AE 3.25D and 2.63D). The number of eyes within ± 0.5D (38.3%) is lower compared to retinoscopy (50.0%), but comparable for ± 1.0D and better for ± 2.0D (61.7% vs. 66.7%, 83.3% vs. 72.2%). Both perform better than TW formula and + 32.0D (ranging from 0.0% for ± 0.5D to 33.3% for ± 2.0D).
conclusionsThe aCL formula is a reliable and accurate tool for determining CL power in aphakic infants. It performed superior to other formula-based and default strategies and is comparable to a retinoscopy. Still, follow-up studies with larger cohorts are needed to validate this outcome.
