Surgical impact of laparoscopic and laparotomic elective ovariectomy on inflammatory and oxidative stress biomarkers in anestrus dogs.

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
objectiveTo compare the systemic inflammatory and oxidative stress responses after elective ovariectomy via open surgery (OPEN) or laparoscopy (LAP) in anestrus bitches. STUDY
designProspective, blinded, randomized clinical trial. Animals A total of 26 healthy bitches.
methodsA total of 26 healthy bitches in anestrus were randomly assigned to undergo either LAP or OPEN ovariectomy (n = 13 per group). Blood samples were collected at four timepoints (preoperative-Tpre, 2 h-T2, 24 h-T24, and 7 days postoperative-T7) for quantification of interleukin-6 (IL-6) and paraoxonase-1 (PON-1), biological antioxidant potential (BAP), and reactive oxygen metabolites (d-ROMs).
resultsIL-6 levels were higher in the OPEN group at Tpre, T24 and T7, while the LAP group exhibited a transient peak at T2 with a return to baseline by T7. PON-1 levels decreased in both groups at T2 but remained lower in the LAP group at T24 and T7. d-ROM levels were higher in the OPEN group, with an increase through T7, whereas the LAP group showed only a transient peak at T24. BAP levels increased in the OPEN group, but not in the LAP group by T7.
conclusionLAP ovariectomy induced a milder and more transient inflammatory and oxidative response compared to OPEN surgery in bitches, likely due to reduced surgical trauma. CLINICAL SIGNIFICANCE: This study included only animals in anestrus. This is the first application of both canine-specific biomarkers of inflammation and canine-validated biomarkers of oxidative stress to compare techniques of elective canine spaying. These findings suggest that minimally invasive ovariectomy attenuates inflammatory and oxidative stress responses compared to OPEN technique in dogs.
