Tourniquet Effect on Patients Undergoing Total Knee Arthroplasty: A Single-Blind, Randomized Controlled Trial.
Trial report in Orthopaedic surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled it.
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
backgroundTourniquet is applied in Total Knee Arthroplasty (TKA) to reduce intraoperative blood loss and improve view of surgical field. However, tourniquet use in TKA is still in dispute. Some researchers find that tourniquet may lead to extra side effects such as aggravated pain and limb swelling, while others consider that tourniquet has no significant adverse impact on clinical outcomes of TKA patients. This trial is conducted to evaluate tourniquet effect on TKA patients.
methodsA prospective, single-blind, randomized controlled trail is adopted with a sample size of 130 knees from August 2020 to February 2023. Patients undergoing TKA are randomly allocated to tourniquet group and non-tourniquet group. Outcomes including quadriceps thickness and stiffness, operation time, total blood loss, intraoperative blood loss, postoperative blood loss, transfusion rate, thigh circumference, knee and thigh VAS, D-Dimer and CRP level, knee function score, patient satisfaction, and complications are evaluated in this trial. Student's t-test, Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test are used in this study.
resultsNo significant difference in demographic information and baseline outcomes were found (p > 0.05). Participants in the tourniquet group had significantly less total blood loss and intraoperative blood loss, more postoperative blood loss, and higher D-Dimer level on postoperative day 3 when compared with non-tourniquet group (p < 0.05). Other outcomes including quadriceps thickness and stiffness, operation time, postoperative blood loss, transfusion rate, thigh circumference, knee and thigh VAS, D-Dimer level on postoperative day 1, CRP level, knee function score, patient satisfaction, and complications showed no significant difference (p > 0.05).
conclusionTourniquet application can effectively reduce intraoperative blood loss and total blood loss, without significant side effects. Hence, we advocate the regular use of tourniquet in primary TKA.
