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

introductionTotal hip replacement is a common and effective surgical intervention for patients with debilitating joint pain but it does represent a significant surgical intervention. For such interventions, blood loss is a potential cause of morbidity and mortality. Optimisation of surgical interventions focuses on reducing such risks. The aim of this study was to determine whether the order of surgical steps, preparing the femur before or after the acetabulum, was associated with the amount of total blood loss in total hip replacement.

methodsWe performed a retrospective study of 100 patients undergoing primary total hip replacement between 2014 and 2018. This was a before and after (interrupted time series) study around the introduction of femur first preparation for total hip replacement in our unit. Fifty patients underwent a standard femoral preparation after placement of the acetabular component. The second 50 patients had the femoral canal prepared and broached prior to the acetabular component. Estimated blood volume and total blood loss associated with the perioperative period were calculated for each patient and a multiple regression analysis performed to account for other patient and surgical variables associated with perioperative blood loss.

resultsThere was a small reduction in total blood loss for the group who underwent femoral preparation prior to acetabular preparation with a mean difference of 39 mls. This difference however was not clinically or statistically (p = 0.392) significant. Gender (p < 0.0001), Body Mass Index (BMI; p < 0.0001), preoperative haematocrit (p < 0.0001), postoperative haematocrit (p < 0.0001) and age (p = 0.004) were the only factors significantly associated with the total volume of blood loss.

conclusionsWhether the femur was prepared before or after the acetabulum did not significantly predict the total volume of blood loss for primary total hip replacement.
