Evaluating the Effect of a Molecular Point-of-Care Test on Acute Respiratory Infections in General Practice: Protocol for a Cluster Randomized Trial.
Article in JMIR research protocols, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06120153 (A Cluster-randomized Trial of Point-of-care PCR Diagnostics of Respiratory Tract Infections in General Practice), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundAcute respiratory infections (ARIs) are frequent reasons for medical consultations in general practice and can lead to unnecessary recontacts. Introducing new point-of-care (POC) polymerase chain reaction (PCR) diagnostic equipment may offer an attractive and efficient way of providing a more precise and exact microbial diagnosis. Successful uptake of POC PCR equipment could potentially lead to a reduction in recontacts with benefits for both staff and patients. However, introducing new diagnostic technology is a complex intervention and several contextual factors may impact the implementation.
objectiveThis study aims to evaluate the effect of POC PCR test availability in general practice on the subsequent (1) number of recontacts to the general practitioner (GP) for patients with symptoms of ARIs (primary outcome) and (2) hospital admissions, deaths, antibiotic prescriptions, health-related quality of life, GP and patient satisfaction, costs, cost-effectiveness, and contextual facilitators and barriers conditioning the implementation process (secondary outcomes).
methodsThis study is a cluster-randomized, crossover, nonblinded superiority trial with a 1:1 allocation ratio between usual care (control) and POC PCR test availability (intervention). Questionnaire data are collected at day 0, 7, 14, and 28 after the initial contact (health-related quality of life, absenteeism and presentism among patients, and patient satisfaction) and after finalization of the study period (GP satisfaction). Data on recontacts, hospital admissions, redeemed antibiotic prescriptions, costs, and deaths will be retrieved from the Danish national registries. The implementation process will be evaluated based on data from interviews with users of POC PCR tests (i.e., GPs, staff, and patients) and from observations in the clinics in line with Medical Research Council guidelines.
resultsAs per the randomized crossover design carried out during September 2023 to March 2024 investigating a sample of 100 GP clinics, we expect to obtain an in-depth and multifaceted understanding of the effects of the availability of the POC PCR test equipment in general practice.
conclusionsThis study will provide valuable information about the diagnostic conditions and possibilities in general practice and provide insights into the organization of primary health care.
