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

purposeThe goal of this study was to analyse the efficacy of blood autotransfusion using a continuous autologous transfusion system in revisions of total hip arthroplasty (THA). We looked at whether administration of allogeneic blood units was reduced in these cases and if there is a difference between cemented and non-cemented revisions.

methodsBetween January 2011 and December 2011, patients being treated with revision THA were included (n = 411). The following parameters were analysed: patient age, gender, weight (kg), height (cm), body mass index (BMI, kg/m(2)), surgical diagnosis, treatment and American Society of Anesthesiologists (ASA) classification score. The difference between pre- and post-operative haemoglobin (Hb, g/dl), amount of peri-operative blood loss (ml), amount of retransfused washed shed blood and amount of allogeneic and/or autologous transfusion (ml) were recorded.

resultsIn both the cemented and non-cemented revision THA groups, there was no significant difference between pre- and post-operative Hb with or without using an autotransfusion system. In 92 of 186 cemented cases using an autologous transfusion system (49.5%) and 38 of 117 non-cemented cases using an autologous transfusion system (32.5%), allogeneic blood transfusion (ABT) was required. Cemented procedures using an autologous transfusion system got significantly more ABTs than non-cemented procedures using an autologous transfusion system (p = 0.0042, odds ratio = 2.035).

conclusionsUse of an autologous transfusion system did not reduce the amount of ABT in revision THA in the patient cohort reported here. In our opinion, general blood management is required before and during surgery to reduce administration of ABT.
