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
This study presents a novel, context-specific mathematical modeling framework for predicting and monitoring COVID-19 transmission in Rwanda, addressing the increasing demand for integrated and data-driven public health decision-support tools. The model incorporates localized epidemiological dynamics, transmission pathways, and major intervention measures, including lockdowns, vaccination, quarantine, and home-based care, which is considered a critical factor influencing disease transmission. Using a system of differential equations, the framework models transition among infected, home-based care, hospitalized, recovered, and deceased populations. The model was calibrated and validated using Rwanda's national COVID-19 surveillance data collected between March 2020 and December 2022, covering multiple epidemic waves and intervention phases. Calibration utilized time-series data on confirmed cases, active infections, hospitalizations, intensive care unit admissions, recoveries, and mortality. Detailed home-based care records improved the estimation of transmission and recovery parameters. Parameter optimization was performed through least-squares fitting and cross-validation techniques. Model performance was assessed using the root mean square error (RMSE) and the coefficient of determination (
