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

objectiveThis study aimed to clarify the association between frailty and the self-reported inability to immediately open a polyethylene terephthalate (PET) bottle cap.

methodsThis cross-sectional study included 427 participants aged 73 and 78 years in City A, Japan. Frailty was assessed using the Kihon Checklist (KCL), and PET bottle cap opening ability was surveyed using a mailed questionnaire. The participants were divided into Immediately Open and Cannot-Immediately Open groups. The frailty status and KCL scores were compared between the groups. Multivariate analysis was used to investigate the association between frailty and the PET bottle cap-opening pattern. The possibility of screening frailty based on the Immediately/Cannot-Immediately Open classification was analyzed using a receiver operating characteristic (ROC) curve.

resultsThe number of frailty in the Cannot-Immediately Open group was significantly greater than the expected count compared to the robust and pre-frailty groups (

conclusionsThe self-reported inability to open a PET bottle cap immediately may be a moderate screening tool for frailty and is associated with many frailty factors.
