Crocodile tear syndrome treated with lacrimal gland incobotulinum toxin A injection: a report of two cases.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Crocodile tear syndrome (CTS) is a late complication of facial nerve palsy characterized by unilateral lacrimation in response to gustatory stimulation. We present 2 cases of patients diagnosed with CTS after recovering from unilateral idiopathic facial nerve palsy. Both patients underwent transconjunctival lacrimal gland incobotulinumtoxinA injection, with doses of 5-16 units. The patients were seen in clinic for post-treatment follow-up at 2 weeks, 3 months, and 6 months. Outcomes were measured by treatment efficacy and adverse drug effects. Following treatment, both patients reported resolution of gustatory lacrimation. The patient treated with 16 U experienced transient ptosis and diplopia following injection, whereas the patient treated with 5-7.5 U experienced no adverse effects.
