Age and sex and their influence on the anatomy of the abdominal aorta and its branches.
Article in Jornal vascular brasileiro, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundIt is not clear how patients' age and sex influence the anatomy of the aorta and its branches.
objectivesTo determine the most frequent anatomical patterns of diameter and angulation of the abdominal aorta and its branches and the influence of patients' sex and age on these patterns.
methodsCT scans with intravenous contrast from 157 patients were analyzed. Diameter and angulations of the abdominal aorta and its branches were measured in individuals of both sexes, classified into five age groups: 20 to 30 years, 31 to 40 years, 41 to 50 years, 51 to 60 years, and 61 to 70 years. Eighteen variables were analyzed: 6 arterial origin angles, 9 arterial diameters, rate of diameter enlargement, and patient's sex and age. RadiAnt 4.2.1 DICOM viewer software was used for measurements.
resultsThe total of 157 CT scans were from 69 men and 88 women. There were statistical differences (p <0.05) in the following results: angle of origin and diameter of the superior mesenteric artery; renal artery angle and diameter; diameter of the common iliac arteries, and diameter and rate of diameter enlargement of the aorta in several segments, but not the segment immediately proximal to the celiac trunk.
conclusionsThe diameters of several aorta segments and of its branches (except the left renal artery) increase progressively with age in both sexes and are larger and have a higher rate of diameter enlargement in men than in women in the same age ranges. Between sexes, the angle of origin of the superior mesenteric artery was larger in men, except between 20 and 30 years, and the angle of origin of the left renal artery was larger in women between 51 and 60 years old.
