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

purposeThis study aimed to investigate the impact of the iris-ciliary angle (ICA) on the position of the implantable collamer lens (ICL) haptic and vault following ICL implantation.

methodsA prospective, observational study was conducted using data from 135 patients who underwent horizontal ICL implantation. Patients were categorized into three groups by ICA: ICA1 (0-32°), ICA2 (32-64°), and ICA3 (64-96°) to compare parameters. The parameters correlated with the distance from the iris root to the end of the ICL haptic (IRH) and vault was analysed respectively. A multiple linear stepwise regression model was constructed to estimate IRH.

resultsThe vault decreased sequentially across the three groups (P < 0.001) and was negatively correlated with ICA (P < 0.001). The proportion of ICL haptic insertion under the ciliary body was significantly higher in the ICA3 group compared with the ICA1 and ICA2 groups (P = 0.039). Stepwise regression analysis showed that IRH = -1.174 + 0.005 × ICA + 0.118 × horizontal sulcus-to-sulcus (STS) distance (adjusted R

conclusionsWhen the ICA is excessively large, the ICL haptic is more likely to be inserted under the ciliary body. An increase in ICA is associated with a greater IRH and a lower vault. KEY MESSAGES: What is known: • More posterior chamber anatomical parameters of eyes are needed to improve the accuracy of predicting the vault. • A negative correlation exists between the iris-ciliary angle (ICA) and vault. WHAT IS NEW: • When the ICA is excessively large, the ICL haptic is more likely to be inserted under the ciliary body. • The ICA is the primary influencing factor when predicting the distance from the iris root to the end of the ICL haptic (IRH).
