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

aimTo examine the feasibility of a food-based, low-energy, low-carbohydrate diet with behavioural support delivered by practice nurses for patients with type 2 diabetes. MATERIALS AND

methodsPeople with type 2 diabetes and a body mass index (BMI) of ≥30 kg/m

resultsForty-eight people were screened, 33 enrolled and 32 followed-up. Mean (±SD) weight loss in the intervention group was 9.5 kg (± 5.4 kg) compared with 2 kg (± 2.5 kg) in the control group (adjusted difference - 7.5 kg [-11.0 to -4.0, P < 0.001]). Mean reduction in HbA1c in the intervention group was 16.3 mmol/mol (± 13.3 mmol/mol) compared with 0.7 mmol/mol (±4.5 mmol/mol) in the control group (difference - 15.7 mmol/mol [-24.1 to -7.3, P < 0.001]).

conclusionsIt is feasible to recruit participants to a food-based, low-energy, low-carbohydrate intervention, for practice nurses to deliver the programme in primary care, and to retain participants in both groups. There is evidence of clinically significant short-term improvements in weight and glycaemic control.
