Reduced body mass index in essential tremor: a study of 382 cases and 392 matched controls.
Article in European journal of neurology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 and purposeThere is mounting evidence that essential tremor (ET) is a neurodegenerative disease. Reduced body mass index (BMI) is a clinical feature of many neurodegenerative diseases, yet there has been little documentation of BMI in patients with ET.
methodsEssential tremor cases and controls were enrolled in a study of the environmental epidemiology of ET at Columbia University Medical Center. Weight and height were measured using a standard protocol; BMI was weight (kg) divided by height (m(2)). Daily calorie count (kcal) was calculated using the Willett Semi-Quantitative Food Frequency Questionnaire. Tremor severity was assessed with a clinical rating scale (total tremor score, range 0-36).
resultsThe 382 ET cases and 392 controls were similar with respect to age, gender and other demographic variables. BMI was lower in ET cases than controls [26.7 ± 5.0 (median = 26.2) vs. 27.7 ± 5.6 (median = 26.7), P = 0.03] despite the fact that the daily caloric intake was marginally higher in ET cases than controls (P = 0.09). In ET cases, BMI was not associated with tremor severity (Spearman's r = -0.02, P = 0.66) but, among younger onset ET cases, longer tremor duration was associated with lower BMI (Spearman's r = -0.14, P = 0.049).
conclusionsThe observed lower BMI in ET is consistent with the neurodegenerative hypothesis of ET. The data also suggest that some mechanism other than decreased daily caloric intake or an involuntary movement-related increased burning of calories is likely to account for this case-control difference.
