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

backgroundThe aim of this study was to confirm the change in haemoglobin A1c consequent to pre-operative donation of autologous blood for elective surgery in patients with diabetes mellitus. MATERIAL AND

methodsFor enrolment in this prospective study, patients had to be scheduled for multiple autologous blood donations at different times and have a haemoglobin A1c level more than 5.8% at the first donation. The values of four factors, haemoglobin, haemoglobin A1c, glycated albumin, and glycated albumin/haemoglobin A1c ratio were determined. Changes in the values of these four factors between before and after the blood donations were calculated.

resultsIn all 24 patients studied, haemoglobin and haemoglobin A1c decreased as a result of the autologous blood donations. The group with a reduced glycated albumin/haemoglobin A1c ratio had short intervals between blood donations. Correlations were observed between donation interval and change in haemoglobin A1c (r=-0.63, P=0.003), and between donation interval and change in the glycated albumin/haemoglobin A1c ratio (r=0.489, P=0.045). DISCUSSION: Haemoglobin A1c levels are likely to be underestimated after autologous blood donation by patients with diabetes mellitus, so glycated albumin may be a better indicator of these patients' glycaemic control.
