"Assessment of an EMR-integrated Onco-Insight hospital-based cancer registry system for data completeness and data entry turnaround time at a tertiary care cancer center in India".
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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: Tata Memorial Centre maintains one of the largest hospital-based cancer registries (HBCR) in India. The registry captures demographic, diagnostic, and treatment information from the electronic medical record (EMR), while Patterns of Cancer Care and Survival Studies (POCSS) collect additional clinical variables including comorbidity, life style, family history of cancer, histopathology, and detailed treatment and follow-up information. As these data are distributed across multiple EMR modules, abstraction is time-consuming. In 2021, the HBCR software was upgraded to the Onco-Insight platform with EMR integration to facilitate automated data retrieval. This study evaluated the platform for data completeness and abstraction turnaround time. Methods: An observational evaluation using an intra-observer comparison design was conducted. Trained registry abstractors collected data using two approaches: conventional manual abstraction and the EMR-integrated Onco-Insight platform. The platform retrieves structured variables directly from the EMR while allowing manual entry for variables unavailable in structured format. Automated mapping from EMR modules to registry variables was implemented for sociodemographic, diagnostic, and treatment domains. Built-in validation rules, range checks, and mandatory field alerts were incorporated to enhance data quality. Data completeness was assessed for sociodemographic, diagnostic, and treatment variables and summarized as the proportion of cases with retrievable information. Data entry turnaround time was defined as the mean time required for abstraction and entry per case and assessed by cancer subsite for both HBCR and POCSS variables. Cases diagnosed and treated in 2021 were evaluated. Results: Of 37,495 registrations in 2021, 32,359 were confirmed cancer cases. Sociodemographic variables were retrieved for all cases (97.59%). Diagnostic variables were retrieved for 13,987 cases (43.22%), and treatment variables for 16,835 cases (50%), followed by manual validation. Manual review was mainly required for patients treated outside the institution, referred between TMC centers, or to distinguish initial therapy from treatment for recurrence or progression. Follow-up information after completion of cancer-directed therapy remained fully manual. Mean abstraction time decreased substantially for HBCR from 27.17 ± 4.40 minutes to 15.07 ± 3.00 minutes. Conclusion: The EMR-integrated Onco-Insight platform reduced abstraction time and improved efficiency while enabling unified entry for HBCR and POCSS. Further EMR standardization, expanded integration, and AI-enabled data extraction could strengthen registry efficiency and cancer surveillance.
