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

backgroundDiabetic patients taking insulin often have suboptimal glucose control, and standard methods of health care delivery are ineffective in improving such control. This study was undertaken to determine if insulin adjustment according to advice provided by telephone by a diabetes nurse educator could lead to better glucose control, as indicated by level of glycated hemoglobin (HbA1c).

methodsThe authors conducted a prospective randomized trial involving 46 insulin-requiring diabetic patients who had poor glucose control (HbA1c of 0.085 or more). Eligible patients were those already taking insulin and receiving endocrinologist-directed care through a diabetes centre and whose most recent HbA1c level was 0.085 or higher. The patients were randomly assigned to receive standard care or to have regular telephone contact with a diabetes nurse educator for advice about adjustment of insulin therapy.

resultsAt baseline there was no statistically significant difference between the 2 groups in terms of HbA1c level (mean [and standard deviation] for standard-care group 0.094 [0.008] and for intervention group 0.096 [0.010]), age, sex, type or duration of diabetes, duration of insulin therapy or complications. After 6 months, the mean HbA1c level in the standard-care group was 0.089 (0.010), which was not significantly different from the mean level at baseline. However, the mean HbA1c level in the intervention group had fallen to 0.078 (0.008), which was significantly lower than both the level at baseline for that group (p < 0.001) and the level for the standard-care group at 6 months (p < 0.01).

interpretationInsulin adjustment according to advice from a diabetes nurse educator is an effective method of improving glucose control in insulin-requiring diabetic patients.
