Revisiting anatomical variants on screening chest radiographs in Indian adolescents: A cross sectional observational pilot study.

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
backgroundKnowledge of normal variation and measurements on a chest radiograph is essential to interpret any abnormality. There is paucity of information about normal measurement ranges and variations in young adolescents, particularly from Indian subcontinent. The aim of this study was to analyze certain normal variations on screening chest radiographs of healthy Indian adolescents and the objectives were to measure/assess (1) degree of inspiration, (2) cardiothoracic ratio (CTR), (3) presence of gastric fundic bubble, (4) fundocupolic distance, (5) presence of splenic flexure, (6) difference in height of diaphragmatic domes and (7) effect of inspiration on the CTR.
methodsDigital chest radiographs obtained during routine medical examinations for all consecutive medical graduate aspirants in the year 2016 at a medical college, were analyzed for the above mentioned parameters using DICOM viewing software.
resultA total of 558 chest radiographs were analyzed. The mean age of the subjects was 18.50 (SD = 1.002) (range: 17-22 years). There were 497 (89.1%) male and 61 (10.9%) female. Degree of inspiration was at 5th, 6th, 7th and 8th ribs in 29 (5.1%), 259 (46.4%), 264 (47.3%) and 6 (1%) respectively. Mean maximum transverse cardiac diameter, internal thoracic diameter, CTR were 1153.22 ± 120.01, 2935.24 ± 224.86 and 0.39 ± 0.03 respectively. Females had slightly higher CTR (0.40 ± 0.035) as compared to the males (0.39 ± 0.032) (
conclusionThe study highlights normal range of inspiration, CT ratio, fundocupolic distance and diaphragmatic dome level difference on screening chest radiographs in healthy Indian adolescents.
