TOURNIQUET USE DOES NOT AFFECT BLEEDING AND SURGICAL TIME IN ROBOTIC-ASSISTED KNEE ARTHROPLASTY.
Article in Acta ortopedica brasileira, 2026. 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
Objective: To compare bleeding and surgical time in patients undergoing Total Knee Arthroplasty (TKA) with robotic assistance with and without the use of a tourniquet. Methods: Retrospective study with analysis of medical records. Patients were divided into two groups: one group in which robotic-assisted TKA was performed using a tourniquet and the other without. The values of hemoglobin (Hb) and hematocrit (Ht) preoperative and 24 hours after surgery, the estimated blood loss, number of transfusions and surgical time were compared between the groups. Results: 108 patients were included, with 59 in the group using a tourniquet and 49 without. There was no difference between the mean Hb and Ht values between the groups preoperatively (p = 0.287 and p = 0.508) and 24 hours (p = 0.252) after surgery. There was also no difference between the estimated blood loss in each group (p = 0.265). Surgical time was not different between groups (p = 0.179). There was no need for transfusions in any patient. Conclusion: Robotic-assisted TKA surgeries, whether performed with or without a tourniquet, showed no significant differences in the drop in Hb and Ht levels 24 hours after surgery, estimated blood loss, transfusions, and surgical time.
