Thyroxine as a Parameter of Stress during Minimally Invasive Surgery.
Observational study in JSLS : Journal of the Society of Laparoendoscopic Surgeons. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aim: The body's hormonal response to stress during minimally invasive surgery has not yet been completely researched in all its aspects, so the aim of this study was to test the body's hormonal response by monitoring the thyroid hormone thyroxine (T4) during laparoscopic cholecystectomy (LC) using standard (12-15 mm/Hg) and low (6-8 mm/Hg) intraabdominal pressure, and in open cholecystectomy (OC). Patients and Methods: This cohort, observational study was conducted in the period from July 2022 to December 2024 and included 110 patients divided into 2 groups: 70 patients who underwent LC, and 40 patients who underwent OC. The first group of patients were divided into 2 subgroups of 35 patients each on the basis of the level of intraabdominal pressure during cholecystectomy (LC with standard, or LC with low intraabdominal pressure). T4 was monitored as the parameter of stress. Results: The comparison between the LC and OC groups in terms of the concentrations of T4 in the postoperative days showed statistically significant higher values of this hormone in the group of patients treated using the open method (OC). Moreover, the body's response to stress was less intense during LC than during OC. The body's response to stress during LC with low insufflation pressure (6-8 mmHg) was lower than during LC with standard insufflation pressure (12-15 mmHg). Conclusion: This study confirms from hormonal aspects the advantages of minimally invasive surgery in comparison with open surgery, and in particular the advantages of LC with low intraabdominal pressure in comparison with standard pressure.
