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

rationaleSodium valproate (VPA) and lamotrigine (LTG) are widely used antiepileptic drugs, disabling postural, and action tremors after using LTG with VPA were reported in 1993. However, in this study, we describe a patient in whom disabling resting-type tremor induced by 2-year use of VPA and LTG. PATIENT CONCERNS: A 50-year old man was referred to department of neurology because of involuntary upper limbs resting-type tremor with high amplitude that had begun 6 months previously and progressively worsened, and he could not work on the day of visit. Furthermore, he had been treated with VPA, LTG, and benzhexol for 2 years as he suffered from twitch of eyelids and facial region, and amantadine, monolithic compound preparation (flupentixol and melitracen) were added in the last 2 months because of tremor and anxiety. However, the treatment had no benefit on improving involuntary movements of the patient. DIAGNOSES: Drug-induced disabling tremor was diagnosed. INTERVENTIONS AND OUTCOMES: LTG, amantadine, and VPA were withdrawn, the remaining 2 drugs, benzhexol and compound preparation (flupentixol and melitracen), were continued to use, and the patient improved in 2.5 months after discontinuation of 3 drugs. There was no recurrence at 6 months follow-up. LESSONS: Considering the wide and long-term utilization of VPA and LTG, healthcare providers should be aware of them as a possible cause of tremor. When necessary, an attempt of discontinuing the suspected drugs should be made to confirm the diagnosis, instead of symptomatic treatment, especially when the adverse event was severe and fatal.
