The effect of a low-energy food foam on appetite measures during a 1-day reduced-energy meal plan.
Trial report in International journal of obesity (2005), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
objectivesWe have previously shown that 500 ml of a foamed drink ('foam') significantly improved appetite versus a non-foamed control. The objectives of this research were to assess the effect of smaller volumes of foams on appetite, and the potential benefits of foam ingestion and its timing on appetite measures in a reduced-energy context. SUBJECTS/
methodsTwo randomized, parallel design studies (pre- and main study) were conducted using healthy adult subjects. Pre-study: 133 subjects (age 18-50 years, body mass index (BMI) 20-32 kg m(-2)) each consumed either 10, 25, 50, 100, 150 or 250 ml foamed meal replacer (~0.2 kcal ml(-1)), 150 min after a fixed breakfast. Main study: four groups of subjects (n=134; age 18-60 years, BMI 22.5-35.0 kg m(-2)) consumed 200 ml/22 kcal foam (based on pre-study results) immediately after main meals (M), after snacks (S), in-between snacks and main meals (I) or not at all (control, C) within 1 day of a reduced-energy meal plan consisting of three main meals and three snacks. Measurements included self-reported appetite (six scales, reported as area under the curve (AUC)) and (main study only) end-of-day appetite questionnaire.
resultsPre-study: the strongest effect on appetite was produced by 250 ml (consistent across scales), whereas 150 ml showed more pronounced effects than 100 and 50 ml in most scales. Volumes 10 and 25 ml had no effects on any scale. Main study: 200 ml foam reduced appetite AUC substantially in all treatments, particularly M (for example, hunger AUC reduced by 35% (P <0.001), 28% (P <0.05) and 20% (P=0.11) for M, S and I, respectively versus C). A strong reduction in 'appetite for a snack' was seen for all timings (all P <0.05). The end-of-day appetite ratings confirmed these findings.
conclusionsModest amounts of a low-energy foam can reduce appetite measures during a 1-day reduced-energy meal plan.
