1 · What the graph read from 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.

2 · The registry

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

backgroundWith the use of tranexamic acid and control of the blood pressure during the operation, total knee arthroplasty (TKA) without tourniquet can be achieved. There is no exact standard for the control level of blood pressure during no tourniquet TKA. We explored the optimal level of blood pressure control during no tourniquet TKA surgery with the use of tranexamic acid in this study.

methodsPatients underwent TKA were divided into three groups: the mean intraoperative systolic blood pressure in group A was < 90 mmHg, 90-100 mmHg in group B, > 100 mmHg in group C. Total blood loss (TBL), intraoperative blood loss, hidden blood loss, transfusion rate, maximum hemoglobin drop, operation time, and postoperative hospitalization days were recorded.

resultsTwo hundred seventy-eight patients were enrolled, 82 in group A, 105 in group B, and 91 in group C. Group A (663.3 ± 46.0 ml) and group B (679.9 ± 57.1 ml) had significantly lower TBL than group C (751.7 ± 56.2 ml). Group A (120.2 ± 18.7 ml) had the lowest intraoperative blood loss than groups B and C. Group C (26.0 ± 4.1 g/l) had the largest Hb change than groups A and B. Group A (62.3 ± 4.7 min) had the shortest operation time. The incidence rate of postoperative hypotension in group A (8, 9.8%) was significantly greater than groups B and C. No significant differences were found in other outcomes.

conclusionThe systolic blood pressure from 90 to 100 mmHg was the optimal strategy for no tourniquet primary TKA with tranexamic acid.
