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

Continuous factor VIII (FVIII) or factor IX (FIX) infusions are commonly used for patients with hemophilia A (HA) or B (HB) undergoing surgery to secure perioperative hemostasis. To describe differences between the initial recovery and subsequent FIX and FVIII levels, and describe clinical outcomes among HB and HA patients receiving perioperative continuous infusion (CI) of recombinant FVIII and FIX concentrates. Retrospective chart review was conducted on 8 consecutive patients with HB and 7 consecutive patients with HA who underwent major surgery between 2014 and 2018 and received continuous infusions of standard half-life factor concentrate. Median initial bolus dose per kilogram was higher for HB compared to HA patients [90.8 (IQR 78.0-98.7) vs. 52.1 (IQR 48.6-55.6) IU/kg], while initial CI dose-rates were similar [4.3 (IQR 3.8-4.6) vs. 4.2 (IQR 3.8-4.4) IU/kg/h]. Median post-bolus recovery was higher for FVIII compared to FIX [1.70 (IQR 1.23-1.75) vs. 0.88 (IQR 0.75-1.00) IU/mL]. Median factor levels also were higher for FVIII on post-operative days 1 to 3. HB patients had greater mean intraoperative estimated blood loss [285.7 (range 0-1000) vs. 142.8 (range 0-400) mL] and longer median length of hospital stay [9 (IQR 8-12) vs. 5 (IQR 4-6.5) days]. Our initial evidence suggests greater in vivo yield of rFVIII compared to rFIX in the perioperative setting. We identified poorer clinical outcomes in this small cohort of perioperative HB patients indicating that they may benefit from a higher CI rate for adequate surgical hemostatic coverage.
