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

purposeManaging hip fracture surgery in patients taking clopidogrel is challenging. The optimal timing for surgery remains unclear. Early surgery in such patients potentially increases peri-operative bleeding, whereas delayed surgery has been shown to be associated with worse postoperative outcomes. The aim of this study was to investigate whether a delay to surgery affects total blood loss, bleeding kinetics, blood transfusion requirements, or post-operative outcomes.

methodsA retrospective monocentric study including all hip fracture patients treated with clopidogrel between 2011 and 2016 (39 patients) was carried out. Patients who underwent delayed surgery after withholding clopidogrel for five days or more, from 2011 to 2013, were compared to patients who benefited from earlier surgical procedures (within 48 hours of admission) from 2014 to 2016.

resultsTotal blood loss, amount of blood transfusion and rate of postoperative complications did not differ between the two groups. However, the timing of bleeding was significantly different; blood loss occurred during the pre-operative phase in the delayed surgery group (p < 0.0001), whereas it occurred during the intra-operative phase in the early surgery group (p = 0.005). The length of the hospital stay was significantly shorter for the early surgery group than for the delayed surgery group: 11 ± three versus 15 ± four days (p = 0.004).

conclusionsEarly surgical treatment of hip fracture in patients receiving clopidogrel does not increase the overall red blood cell loss or the transfusion requirement, but may affect the timing of blood transfusion. Hip fracture surgery should preferably be performed without delay in patients taking clopidogrel.
