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

backgroundTo compare the accuracy of toric intraocular lens (IOL) calculation using simulated keratometry (SimK) obtained from two different devices in cataract eyes with central or paracentral preoperative corneal irregular astigmatism.

methodsPatients with cataract and irregular preoperative corneal astigmatism who underwent uneventful cataract phacoemulsification with toric IOL implantation were retrospectively enrolled. Irregular preoperative corneal astigmatism was confirmed by corneal topography. SimK was obtained using swept-source optical biometry (IOLMaster700, SimK

resultsA total of 111 eyes (92 patients) were included, including 52 eyes with central and 59 eyes with paracentral irregular astigmatism. Postoperative astigmatism significantly decreased in both groups (both P < .01). Patients in the central irregular astigmatism group had significantly greater postoperative refractive astigmatism than those in the paracentral group. Comparison of SimK-based predictions between the two devices revealed that K

conclusionsToric IOL implantation effectively reduces corneal irregular astigmatism. SimK obtained from optical biometry (IOLMaster 700) demonstrated superior accuracy in predicting postoperative refractive astigmatism compared to Scheimpflug topography (Pentacam HR) in eyes with central irregular astigmatism; this advantage was not observed in paracentral irregularity and should not be generalized to all irregular corneas.
