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 AND

objectivesOropharyngeal dysphagia (OD), a dysfunction in swallowing food or drink, can result from various diseases and adverse drug reactions. OD is a risk factor for aspiration pneumonia (AP). However, the specific drugs causing OD and their incidence rates are not fully understood. This study aimed to identify drugs associated with OD, their incidence rates, and AP risk factors in patients taking these drugs on the basis of the information provided in package inserts.

methodsThis study identified candidate dysphagia-inducing drugs (CDIDs) from Japanese package inserts that listed OD as an adverse reaction. The age, sex, medications, and comorbidities of patients taking CDIDs were analyzed using the JammNet insurance database, purchased from JammNet Co., Ltd. (Tokyo, Japan).

resultsOverall, 54 ingredients were identified as CDIDs. Out of 24,276 patients taking CDIDs, 146 (0.6%) were diagnosed with OD and 76 (0.3%) with AP. Among those with AP, 23 patients (30%) also had OD. OD or AP occurred in patients taking 28 (52%) of the 54 target ingredients. In addition, 13 ingredients had an adverse reaction incidence of 1% or greater for either condition. The top five CDIDs with the highest incidence rates for each diagnosis were clobazam, baclofen, zonisamide, tiapride hydrochloride, and topiramate. Incidence rates of OD and AP were significantly higher with multiple CDIDs than with a single drug (p < 0.05). Logistic regression analysis showed that AP occurrence was significantly associated with males, late-stage elderly individuals, a diagnosis of OD, and constipation.

conclusionsThe results of this study suggest that careful attention should be given to the risk of AP when prescribing CDIDs, particularly for elderly male patients.
