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

Tearing is a very common symptom in ophthalmic practice; however, this issue is commonly overlooked. The authors describe the case of a patient with chronic unilateral epiphora that had been neglected for 8 y; lacrimal system workup was performed for this patient only because of dacryocystitis evolvement. Following the diagnosis of nasolacrimal duct blockage, dacryocystorhinostomy was indicated. Intraoperative abnormal mucosa was subjected to biopsy, and a diagnosis of squamous cell carcinoma in the lacrimal sac was established. Extended tumor excision was performed for the patient and adjuvant radiotherapy was administered, without any recurrence till the 2-year follow-up. The present report highlights the relevance of a detailed evaluation for determining the underlying causes of tearing, especially in chronic unilateral presentation. The consideration of potential malignancy in such cases could prevent delayed diagnosis of uncommon but potentially life-threatening malignancies of the lacrimal drainage system.
