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
Background: Acute abdomen is a common clinical emergency requiring rapid and accurate diagnosis. Abdominal radiography (AR) remains a first-line imaging tool due to its accessibility and specificity for certain conditions, but minimizing radiation exposure is a persistent concern. This study aimed to evaluate the effectiveness of a low-dose abdominal radiography (LDAR) protocol for patients with acute abdomen. Methods: A total of 354 patients (189 men, 165 women; mean age, 50 years) who underwent acute abdominal surgery after being admitted with an acute abdomen were randomly assigned to a LDAR group [121 kVp, with automatic exposure control (AEC)] and a standard-dose abdominal radiography group (SDAR; 81 kVp, with AEC) group. Plain LDAR and SDAR were independently reviewed by two radiologists for the overimpression, diaphragm, and intestinal gas, and program analysis was performed in a delayed manner, with diaphragm sharpness computed by Matlab. The mean values of parameters assessed by the two radiologists were compared. Results: All images, from both the LDAR group and the SDAR group, were appropriate for direct diagnosis. No patients were exposed to additional doses in this study. The imaging quality of plain LDAR was superior to that of the plain SDAR, with higher mean scores for overimpression (4.97±0.18 Conclusions: The LDAR with 121 kVp could significantly reduce radiation dose while maintaining comparable image quality to that of SDAR, holding value in specific clinical scenarios.
