Laparoscopic Sleeve Gastrectomy Improves Olfaction Sensitivity in Morbidly Obese Patients.
Article in Obesity surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 2 of them syntheses that pooled 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.
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
backgroundOlfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy.
methodA laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit.
resultsAnalyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all).
conclusionsHere, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.
