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

Background: Congenital nasolacrimal duct obstruction (CNLDO) is a common cause of epiphora in children. Lacrimal intubation is often performed when probing fails, but the optimal approach remains debated. This study compared the outcomes of nasal endoscopy-guided and blind closed lacrimal intubation in pediatric patients with CNLDO. Methods: This prospective comparative study (single-center retrospectively registered) was conducted on 63 eyes of 39 children under 16 years. Participants were randomly assigned to blind closed intubation ( Results: Operation time was significantly lower in the nasal endoscopy-guided group than that in the closed group ( Conclusions: Both blind and endoscopic lacrimal intubation achieved high success rates in children with CNLDO. The nasal endoscopy-guided technique shortened operative time and offered better visualization, but overall outcomes and satisfaction were comparable.
