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 use of computed tomography (CT) has increased tremendously, and at the same time, it has also raised concerns about potential risks such as cataracts and cancers among patients and occupational workers. The majority of studies reported the entrance surface dose to the eyes, thyroid, and breast within the CT scan field of view, without shielding. In the present study, we aim to measure the scatter doses (outside the scan area) to the eyes, thyroid, and breast during a plain abdominal CT scan with (0.5 mm lead equivalence) and without shielding. MATERIALS AND
methodsA cross-sectional analytical study was designed for participants (n = 93; 51 males (55%), 42 females (45%)) and with shielding (n = 93; 52 males (56%), 41 females (44%)) who underwent plain abdominal CT scans. Scatter radiation doses to the eyes, thyroid, and breast were measured using a CaSO₄:Dy Teflon thermoluminescence dosimeter.
resultsThe measured mean ± standard deviation value of without and with shielding are as follows: right eye (0.126 ± 0.170 mSv, 0.030 ± 0.035 mSv), left eye (0.112 ± 0.133 mSv, 0.029 ± 0.035 mSv), right thyroid (0.203 ± 0.296 mSv, 0.102 ± 0.089 mSv), left thyroid (0.210 ± 0.282 mSv, 0.112 ± 0.085 mSv), right breast (0.658 ± 0.863 mSv, 0.287 ± 0.218 mSv), and left breast (0.626 ± 0.842 mSv, 0.273 ± 0.199 mSv). Scatter doses to the eyes were reduced by 74-75% (p < 0.0001), the thyroid by 47-50% (p < 0.0001), and the breast by 56% (p < 0.0001) with shielding compared to scatter doses received by these organs without shielding.
conclusionsThe present study indicates that organs outside the CT scan area received scatter radiation. Shielding significantly reduced the doses to the eyes, thyroid, and breast. Hence, the findings support the use of shielding whenever feasible during a CT scan.
