Patient-size based dose optimization in projection radiography examinations: A BMI-guided approach.
Article in Journal of applied clinical medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThe increasing prevalence of obesity poses challenges for dose optimization in projection radiography due to greater anatomical thickness in overweight and obese patients worldwide. Diagnostic reference levels (DRLs) alone may not adequately account for variations in body habitus, potentially leading to suboptimal patient protection. This study aimed to explore benchmark doses (BMDs) based on patient body mass index (BMI) for projection radiography examinations of major anatomical regions in Sri Lanka, providing a complementary approach for dose optimization alongside DRLs.
methodsThis prospective study included 1989 adult patients (≥18 years) undergoing abdomen anteroposterior (AP), chest posteroanterior (PA), kidney-ureter-bladder (KUB) AP, lumbar spine AP, lumbar spine lateral (LAT), and pelvis AP examinations at six major tertiary care hospitals. For each examination, patient demographics (age, weight, height, and BMI) and exposure parameters (kilovoltage peak [kVp] and tube current-exposure time product [mAs]) were recorded, and the patient doses in terms of kerma-area product (P
resultsThe results showed a progressive increase in BMI-based BMDs across BMI categories for all examinations studied. BMI-based BMDs (in Gy.cm
conclusionThese findings underscore the importance of BMI-based BMDs as an effective tool for personalized dose optimization, accounting for variations in patient body habitus. Their integration into clinical practice, alongside DRLs, could enhance patient protection and promote good radiographic practices. Furthermore, the findings underscore the need for the introduction of international guidelines for DRLs in intervals of BMI to ensure standardized implementation across countries.
