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

purposeThis study was performed to assess the effectiveness of the combined intravenous and intra-articular tranexamic acid (TXA) regimen in total knee arthroplasty (TKA).

methodsThe perioperative blood loss in 75 consecutive patients undergoing unilateral TKA that received both 1000 mg of TXA intravenously and 1000 mg of intra-articular TXA (combined TXA group) was compared with a consecutive series of 77 patients that received 1000 mg of TXA intravenously (intravenous TXA group). An additional 1000 mg of intravenous TXA was administered 6 h after the initial administration in both groups. Neither a pneumatic tourniquet nor drain was used. The primary outcome was the perioperative blood loss at 3 days after TKA calculated using the blood volume and change in haemoglobin from the preoperative value.

resultsThe perioperative blood loss was significantly lower in the combined TXA group at 3 days after TKA than the intravenous TXA group (686 ± 303 vs. 830 ± 317 mL; 95% CI 44-244 mL; p = 0.0049). The perioperative blood loss was also lower in the combined TXA group at 1 and 7 days after TKA (374 ± 265 vs. 459 ± 226 mL; 95% CI 7-165 mL; p = 0.034 and 751 ± 320 vs. 871 ± 327 mL; 95% CI 16-224 mL; p = 0.024, respectively). No thrombotic events were observed during the study periods.

conclusionsCombined intra-articular and intravenous TXA regimen significantly reduced perioperative blood loss compared with only intravenous TXA until 7 days after TKA.
