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

purposeThe PROMISS randomized-controlled trial (RCT) showed that personalized dietary advice, regarding, for instance, protein-enriched food products, increased protein intake among community-dwelling older adults with a low habitual protein intake. This secondary analysis evaluates how the dietary advice aimed solely at increasing protein intake affects the intake of other (macro)nutrients, saturated fat, sugars, and dietary fiber.

methodsCommunity-dwelling older adults (n = 260, mean age 75 years, 53% women) in Finland and the Netherlands with a habitual protein intake < 1.0 g/kg adjusted body weight/day were included in this secondary analysis. The two intervention groups (n = 175) received personalized dietary advice for 6 months to increase protein intake. The control group (n = 85) received no intervention. Nutrient intake was evaluated with 24 h recalls and a 3-day food record at baseline and follow-up.

resultsMacronutrient intake at baseline was similar across groups. In addition to an increase in protein, the intervention groups showed a significant increase in carbohydrate intake relative to the control group, with no change in the intake of total fat, saturated fat, sugars, or dietary fiber. An increase in energy intake was associated with an increase in protein intake [r = .55 (95% CI 0.46-0.63)] but not with relative weight gain [r = 0.03 (95% CI - 0.09 to 0.16)].

conclusionDietary advice to increase protein intake increased also the intake of carbohydrates, but intakes of fiber, sugars, and (saturated) fat remained at baseline levels.
