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

backgroundCyclic vomiting syndrome (CVS) can impair nutritional status due to recurrent episodes of nausea and vomiting, yet systematic data are lacking. We aimed to evaluate nutritional status in adults with CVS using validated assessment tools.

methodsIn a prospective study of adults diagnosed with CVS based on Rome IV criteria, nutritional status was evaluated using the Patient-Generated Subjective Global Assessment Short Form (PG-SGA-SF) completed by participants, the PG-SGA completed by a Registered Dietitian Nutritionist (RDN) and the Malnutrition Screening Tool (MST). KEY

resultsAmong 80 participants (mean age 39 ± 16 years) 77.5% (n = 62) were female, and 85% (n = 68) had moderate-to-severe CVS. Based on the PG-SGA-SF, 70% (n = 56) were at risk of malnutrition (42.5%, n = 34 severe; 27.5%, n = 22 moderate). More than half (41; 51%) were at risk for malnutrition (MST score ≥ 2). Despite this, 27% (n = 22) were obese, and 20% (n = 16) were overweight. Mean BMI did not differ between well-nourished and malnourished participants (28.4 ± 8.2 kg/m CONCLUSIONS AND INFERENCES: Most adults with CVS met criteria for malnutrition, indicating a need for referral to an RDN. BMI should not be used as a screening tool for malnutrition, and mechanisms underlying obesity in CVS warrant further investigation.
