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

Population ageing and the limited mental healthcare human resources are widening the service gap between older people's mental healthcare needs and the system's capacity in Hong Kong. Scaling up services through integration into the primary care system remains the main strategy to address unmet needs. In this study, we co-developed a primary mental healthcare system for older people with common mental health disorders with 33 stakeholders, including representatives from the government, primary healthcare services, charities, professionals, service users, caregivers and researchers. The study had three phases, including (1) rapid situational analysis (RSA) and survey to synthesise key elements and challenges of the existing service, (2) three rounds of theory of change (ToC) workshops (online) with stakeholders and (3) reach consensus and finalise the ToC map. A shared vision of
