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: Insomnia is a prevalent sleep disorder among older adults, associated with fatigue, cognitive decline, and poor physical and mental health. Concise instruments such as the Insomnia Severity Index (ISI) are valuable for screening and evaluation. This study aimed to validate the Indonesian version of the ISI in older adults. Methods: This study used a cross-sectional survey conducted in multiple health centers and hospitals. The ISI was adapted into Indonesian following the Consensus-based Standards for the Selection of Health Measurement Instruments guidelines. Construct validity was examined using Exploratory Factor Analysis, while reliability was assessed using Cronbach's alpha and intraclass correlation coefficients (ICC). Results: A total of 510 older adults (mean age 69.3 years, 81.4% female) participated. Item-total correlations were strong ( Conclusion: This study demonstrates that the ISI is a valid and reliable instrument for evaluating perceived insomnia severity among older adults in Indonesia. Its ease of use and strong psychometric properties make it an invaluable tool for healthcare practitioners in routine screening and clinical practice.
