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

aimsTo determine the blood transfusion rates following shoulder arthroplasty and to establish risk factors associated with increased risk of transfusion. MATERIALS AND

methodsAll shoulder arthroplasty cases performed between January 2012 and March 2017 in a tertiary upper limb unit were identified. Patients who received perioperative tranexamic acid were excluded. Retrospective review of case notes was completed to identify transfusion rate and risk factors. Univariate and multivariate analysis were performed to analyse the association between risk factors and transfusion rate.

resultsFive hundred and thirty-seven shoulder arthroplasties performed in 474 patients were included. Peri- or post-operative transfusion was required in 21 cases (3.9%). Univariate analysis suggested significant association with age (p = 0.005), female sex (0.015), preoperative haemoglobin/haematocrit (p < 0.001), perioperative drop in haemoglobin (p < 0.001), ASA grade (p < 0.001) and transfusion rate. Only perioperative drop in haemoglobin (p < 0.001) and American Society of Anaesthesiologist score (ASA) grade (p = 0.039) retained significance on multivariable analysis.

conclusionsThe blood transfusion rate following shoulder arthroplasty was 3.9%. Greater perioperative drop in haemoglobin and higher ASA grade were associated with increased risk of transfusion on multivariate analysis.
