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

Although the measurement of hemoglobin A1c (HbA1c) using high-performance liquid chromatography (HPLC) is routinely used to estimate average blood glucose levels, it may not be accurately measured for various reasons, such as alteration of red blood cell lifespan and the existence of hemoglobin variants; including hemoglobin F (HbF). Here, we report cases of fulminant type 1 and type 2 diabetes mellitus in which HbA1c levels were unmeasurable because of increased labile HbA1c levels. Case 1 involved a 73-year-old man with fulminant type 1 diabetes mellitus, who was brought to our hospital with diabetic ketoacidosis. The patient's blood glucose level was 994 mg/dL, and HbA1c was unmeasurable, which turned out to be 6.2% on the next day when the blood glucose level was normalized. Case 2 involved a 72-year-old man with type 2 diabetes mellitus, whose blood glucose level was 767 mg/dL, and HbA1c was unmeasurable, which turned out to be 17.9% the following day. In both cases, the chromatograms showed that the HbA1c peaks overlapped with large labile HbA1c peaks, which decreased the next day. It is important to keep in mind that HbA1c levels may not be accurately measured in cases of extreme hyperglycemia because of an increase in labile HbA1c, regardless of the absolute HbA1c level.
