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

objectiveA systematic review and meta-analysis was conducted to explore the efficacy of tranexamic acid (TXA) in reducing transfusion events in patients undergoing percutaneous nephrolithotomy (PCNL).

methodsPubMed, Web of Science, Embase, EBSCO, and Cochrane library databases from January 1980 to October 2019 were searched for randomized controlled trials (RCTs) that assessed TXA efficacy in reducing transfusion events during PCNL. Intervention treatments include using TXA compared with placebo (or no intervention) for patients who underwent PCNL. The search strategy and study selection process were managed in accordance with the PRISMA statement.

resultsSix RCTs are included in the meta-analysis. Overall, TXA intervention groups showed a significant reduction in blood transfusion events (RR = 0.34; 95% confidence interval [CI] = 0.19 to 0.62), hemoglobin decrease (MD = -0.80; 95% CI = -1.32 to -0.28), operative time (MD = -12.62; 95% CI = -15.62 to -9.61), and length of hospital stay (MD = -0.73; 95% CI = -1.36 to -0.10) compared with control groups after PCNL. However, TXA had no substantial impact on the rate of stone clearance (RR = 1.10; 95% CI = 1.00 to 1.21).

conclusionsTXA can effectively reduce the transfusion rate and blood loss during PCNL.
