A behavioural intervention incorporating specific glycaemic index goals improves dietary quality, weight control and glycaemic control in adults with type 2 diabetes.

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.
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
objectiveA lower glycaemic index (GI) diet is associated with a reduction in glycosylated Hb (HbA(1c)) in people with diabetes. Yet, little research has been conducted to determine the effects of specific goals regarding consumption of low GI (LGI) foods on diabetes outcomes. The present study evaluated a behavioural intervention on dietary intake, weight status and HbA(1c), which included a goal to consume either six or eight servings of LGI foods daily.
designA parallel two-group design was used. Following the 5-week intervention, participants were randomly assigned to the group of six (n 15) or eight (n 20) servings of LGI foods daily and followed up for 8 weeks. Dietary intake was assessed using the mean of 4 d food records.
settingA metropolitan community in the USA. SUBJECTS: Individuals aged 40-65 years with type 2 diabetes of ≥1 year and HbA(1c) ≥ 7·0 % were eligible.
resultsThere was no significant difference between goal difficulty groups with regard to GI servings at the end of the study. However, mean consumption of LGI foods increased by 2·05 (SE 0·47) and 1·65 (SE 0·40) servings per 4184 kJ in the six (P < 0·001) and eight (P < 0·001) LGI serving groups, respectively. For all participants combined, there were significant decreases in mean HbA(1c) (-0·58 (SE 0·21) %; P = 0·01), weight (-2·30 (SE 0·78) kg; P = 0·01), BMI (-0·80 (SE 0·29) kg/m(2); P = 0·01) and waist circumference (-2·36 (SE 0·81) cm; P = 0·01).
conclusionsAn intervention including a specific goal to consume six to eight servings of LGI foods daily can improve diabetes outcomes. Clinicians should help patients set specific targets for dietary change and identify ways of achieving those goals.
