Design and Photometric Optimization of a Low-Cost Phototherapy Bed for Neonatal Jaundice.
Article in Annals of biomedical engineering, 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
purposeNeonatal jaundice is a common condition that can lead to serious complications if left untreated. Although phototherapy is the standard treatment, existing devices are often costly, energy-intensive and fail to deliver the required intensity or provide uniform irradiance, particularly in low-resource settings. This study aims to design and optimize a low-cost, energy-efficient phototherapy bed that meets clinical requirements for irradiance intensity and spatial uniformity.
methodsA multi-objective photometric optimization approach was applied to design the phototherapy bed, focusing on balancing irradiance intensity, glare control, and dark spot avoidance. Simulations were performed using a Lambertian emission model to determine the ideal LED configuration. Different LED grid layouts with varying LED spacing were simulated. The optical properties of all materials, including the LEDs, diffuser, bed flat, and mattress, were tested. The device design and assembly are described.
resultsThe optimal LED configuration, a hexagonal grid with approximately 9 cm spacing, yielded the best performance. The measurement verification for the Lambertian emission model showed strong agreement with the simulation results. Prototype testing achieved a mean irradiance of 44.78 μW/cm
conclusionsThis system, with a material cost of approximately $80, offers an affordable and clinically effective solution for neonatal jaundice therapy in low-resource settings. It supports home treatment and promotes mother-infant bonding. The proposed optimization methodology can serve as a design reference for future light-based therapeutic systems.
