Evidence-based team intervention to reduce diagnostic errors in anaemia and CKD diagnoses in primary care: protocol for a stepped-wedge cluster RCT.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05735314 (A New Combination of Evidence-Based Interventions to Improve Primary Care Diagnostic Safety and Efficiency), 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
introductionDiagnostic errors in primary care are common, particularly in the interpretation and follow-up of abnormal haemoglobin (Hgb) and estimated glomerular filtration rate (eGFR) results. These errors frequently result in missed or delayed diagnoses of serious conditions such as anaemia and chronic kidney disease. This protocol describes a stepped-wedge cluster randomised controlled trial designed to evaluate a novel, evidence-based, team-based intervention aimed at improving diagnostic safety and efficiency. METHODS AND ANALYSIS: The study will be conducted across 12 University of Texas Physicians (UTPs) primary care clinics in Houston, Texas, USA. Adult patients (≥18 years) with newly identified abnormal Hgb or eGFR results will be eligible for inclusion. The intervention integrates automated tracking of abnormal laboratory results, nurse navigators to support patient follow-up and engagement, and clinical pathologists to provide diagnostic guidance to primary care providers. The primary outcome is diagnostic safety, defined as the proportion of patients who receive a correct diagnosis within 6 months. Secondary outcomes include diagnostic efficiency, appropriate test utilisation, cost-effectiveness, patient activation and implementation metrics such as acceptability, fidelity and sustainability. The study will also explore barriers and facilitators to successful implementation using mixed-methods evaluation. ETHICS AND DISSEMINATION: This trial has been approved by the Institutional Review Board at The University of Texas Health Science Center at Houston. Study results will be disseminated through peer-reviewed publications and conference presentations, and findings will be reported to UTP leadership to inform potential system-wide implementation. TRIAL REGISTRATION NUMBER: NCT05735314.
