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.

Abstract

objectiveA meta-analysis was performed to investigate the effectiveness and safety of tranexamic acid (TXA) for the treatment of blood loss after a bilateral total knee arthroplasty (TKA).

methodsPatients prepared for bilateral TKA and intervention including TXA versus placebo were comprehensively retrieved from MEDLINE (PubMed), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science from the time of the establishment of these databases to January 2016. The outcomes were all calculated by Stata 12.0 software. The continuous endpoints (total blood loss and blood loss in drainage) were calculated as mean difference (MD) and 95% confidence intervals (CIs). Binary variables (the need for transfusion, and the occurrence of deep venous thrombosis [DVT]) were calculated as relative risk (RR) with 95% CIs.

resultsPooled results revealed that treatment with TXA associated with less need for transfusion (P = 0.000) and the value of Hb drop postoperatively (P = 0.290) after bilateral TKA. The results also indicated that TXA can decrease the total blood loss and blood loss in drainage after bilateral TKA (P < 0.05). Meanwhile, TXA can decrease the blood units transfused per patient by 1.23 U (P = 0.001). There is no statistically significant difference in terms of the occurrence of DVT between the 2 groups (P = 0.461).

conclusionBased on the current evidence, TXA can decrease the need for transfusion and the total blood loss without increasing the occurrence of DVT, and its administration is recommended routinely in bilateral TKA.
