Liver measurements on computed tomography: a guide for day-to-day practice in the Saudi population.
Article in Annals of Saudi medicine. 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
backgroundLiver size can indicate the presence of liver diseases such as cirrhosis, hepatitis, and malignancy. Accurate assessment of liver span is essential for the early identification of liver pathologies.
objectivesThe objective of this study is to establish a reference value for the average liver size of the Saudi population using abdominal computed tomography (CT) scans. A secondary objective of the study is to explore the correlations of demographic factors and comorbidities with liver size.
designA retrospective cross-sectional study.
settingTertiary healthcare center in Riyadh, Saudi Arabia. PATIENTS AND
methodsA retrospective cross-sectional analysis of liver span, liver width, and spleen span was performed. The maximum oblique craniocaudal (MaxCC) length and transverse width of the liver and maximum length of the spleen were obtained in coronal view. The demographic characteristics and comorbidities of patients were collected.
main outcome measuresLiver span, width, and spleen span of the study population. In addition to demographic characteristics and comorbidities that were correlates of larger liver size. SAMPLE SIZE: 2500 adult patients who underwent CT scans for conditions unrelated to liver disease.
resultsThe mean (SD) liver span of the study population was 17.6 cm (2.4), while mean liver width was 18.9 cm (2.8). Multivariate analysis showed that a larger liver span was significantly correlated with increased age, height, a diagnosis of diabetes, as well as fatty liver and a larger BMI score.
conclusionsMeasurement of the liver span using the MaxCC length and liver width is a simple method for routine clinical screening. The values established are useful in screening for liver disease that causes hepatomegaly and should therefore be used more frequently in a clinical setting in CT imaging. LIMITATIONS: Retrospective single-center design and reliance on CT-based diagnosis of fatty liver, which may not detect subclinical steatohepatitis.
