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

aimTo test the effect of nurse-led Internet-based cognitive behavioural therapy for insomnia (I-CBTI), tailored for patients with cardiovascular disease (CVD), with a 6-month follow-up.

designA two-arm parallel-group randomized controlled trial (RCT) registered at clinicaltrials.gov (NTC03938805) and reported according to the CONSORT checklist.

methodsForty-eight patients (mean age 72 years, 65% men) diagnosed with CVD and insomnia were randomized to either 9-week nurse-led I-CBTI with support, or an Internet-based self-study programme without support (control group). Insomnia Severity Index (ISI) and Short Form Health Survey (SF-12) were used as primary and secondary outcomes.

resultsISI showed a significant treatment effect of I-CBTI compared to the control group at 9-week follow-up. The mean ISI score in the I-CBTI group at 9 weeks post-treatment was maintained at the 6-month follow-up. Patients' adherence to I-CBTI was associated with a better effect on both the ISI and SF-12.
