After early release of tourniquet in total knee arthroplasty, should it be reinflated or kept deflated? A randomized trial.

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
purposeThis study was undertaken to determine the efficacy of reinflation of the tourniquet after its early release in TKA compared to early release alone, in terms of surgical field visualization and operative time. We also questioned whether tourniquet reinflation after its early release is safe, with respect to post-operative blood loss, post-operative pain and other tourniquet-related complications.
methodsTwo hundred and six patients undergoing TKA were randomly allocated to either the early release (deflation) group (n = 105) or reinflation after early release (reinflation) group (n = 101). Efficacy was measured in terms of surgical field visualization, specifically the number of wound clearances, and operative time. Safety outcomes were drained volume, decline in haemoglobin on post-operative days 2 and 5, the frequency of transfusion, knee and thigh pain visual analog scale, local wound complications, tourniquet site complications and other complications, including infection, deep vein thrombosis and pulmonary embolism.
resultsSurgical field visualization was better in the reinflation group; however, the operative time did not differ between the two groups. There were no differences between the two groups in post-operative blood loss, decline in haemoglobin on days 2 and 5, transfusion rate, pain level, local complications and other complications.
conclusionReinflation of tourniquet is a safe alternative to its early release after deflation in that it improves surgical field visualization during TKA. LEVEL OF EVIDENCE: Therapeutic study, Level I.
