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
Purpose: After coronary artery bypass graft surgery (CABG), patients may experience pain and numbness in the anterior chest wall. These symptoms can negatively impact patients' quality of life and overall cardiac surgery satisfaction. This study investigates the effect of monopolar electrocautery output power, for hemostasis in the remaining internal thoracic wall after harvesting of the Internal Thoracic Artery (ITA), on postoperative pain in the anterior chest wall. Patients and Methods: This paper examined 100 patients who had ITA harvesting during CABG in a Cardiovascular Surgery Clinic. Patients who were able to comply with postoperative pain tests and had sufficient mental and visual capacity were included in the study. In Group 1 (n: 50) patient, after the ITA was harvested, hemostasis was performed with 20 watt cautery power on the inner wall of the thorax. In Group 2 (n: 50) patients, hemostasis was performed with 40 watt electrocautery power. It was investigated whether there was a difference between these two groups in terms of postoperative drainage amounts and pain in the anterior chest wall with Behavioral Pain Scale (BPS) and Visual Analogue Scale (VAS). Results: No statistically significant difference between Group 1 and Group 2 regarding demographic data and postoperative drainage amounts. However, in Group 1, in patients who hemostasis performed in the inner wall of the thorax with a low cautery power of 20 watts, postoperative pain was statistically significantly lower than in Group 2 in terms of BPS and VAS. Conclusion: After harvesting of the ITA, hemostasis of the thoracic wall with 20 watt low cautery power does not affect the postoperative drainage. Additionally, these patients experience less postoperative pain due to less thermal damage after CABG. Furthermore, lower postoperative pain levels may reduce treatment costs by reducing analgesic requirements and intensive care duration.
