Clinical outcomes and prognostic factors in patients with nasolacrimal duct obstruction or stenosis using dacryoendoscopy.
Trial report in BMJ open ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05999058 (Clinical Characteristics and Treatment Outcomes of Nasolacrimal Duct Obstruction Using Dacryoendoscopy), which is not on this map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
objectiveTo evaluate the effectiveness of dacryoendoscopic-assisted laser dacryoplasty with silicone intubation (DLDI) for the management of nasolacrimal duct obstruction (NLDO) or stenosis, and to identify the factors associated with DLDI failure. METHODS AND ANALYSIS: This study was designed as a prospective, single-centre cohort study. Patients with NLDO or stenosis who underwent DLDI from December 2019 to December 2021 at Tianjin Eye Hospital were considered for enrolment. The Kaplan-Meier estimator was used to assess the anatomical and functional success rate of DLDI within 2 years follow-up after removal of the silicone stent. Cox proportional hazards regression models were used to identify risk factors for treatment failure.
results170, 174 and 178 eyes were included in Groups A (proximal NLDO), B (distal NLDO) and C (nasolacrimal duct stenosis), respectively. The overall anatomical success rate was 84.8% for the entire cohort at the 2-year follow-up. The cumulative anatomical or functional success rate for Groups B and C was significantly higher than that for Group A. In the multivariable model, a higher risk of failed DLDI surgery was associated with a history of chronic dacryocystitis (HR=3.07; p<0.001) and a longer duration of epiphora than 1 year (HR=2.67; p<0.001). Of the 522 eyes, 37 patients (7.1%) had surgery-related complications.
conclusionsDLDI is an effective minimally invasive technique for treatment in patients with distal NLDO or stenosis. Factors associated with a higher risk of reoperation include a longer duration of epiphora and a history of chronic dacryocystitis. TRIAL REGISTRATION NUMBER: NCT05999058.
