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

backgroundLow-carbohydrate diets have been shown to effectively improve the metabolic status of patients with type 2 diabetes mellitus. However, patients may find it challenging to maintain a strict low-carbohydrate diet. The objective of this study was to determine if a one-meal, low-carbohydrate diet is as effective in improving metabolic status as a conventional, energy-restricted diet among patients with type 2 diabetes mellitus.

methodsIn this 12-week randomized controlled study, the primary endpoint was differences in the changes of plasma glycosylated hemoglobin (HbA1c) levels between the two experimental groups. Since the two groups had differences in body weight, body mass index, and waist circumference, propensity score matching was used to assess HbA1c outcomes via cohort pairs according to age, sex, body weight, HbA1c level, and waist circumference.

resultsThere were no differences in the changes in HbA1c between the two groups (P = 0.95). In addition, there were no differences in the changes in glycated albumin, 1,5-anhydroglucitol, lipid profile, body weight, waist circumference, and fat mass between the two groups. The mini low-carbohydrate diet group had an increased protein intake (P = 0.0085), as compared with the control group. However, neither group showed changes in their Diabetes Treatment Satisfaction Questionnaire score.

conclusionEither diet would be effective for improving the metabolic status of this study population.
