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

backgroundAlterations in taste/smell after bariatric surgery have been observed, but few data is available. Some authors documented these changes and their role on weight loss but there is no evidence after laparoscopic sleeve gastrectomy (LSG).

methodsCohort study with patients submitted to laparoscopic gastric bypass (LGBP) and LSG that were asked to participate in a validated survey. The primary objective was to determinate the differences between procedures for taste and smell changes; a demographic and anthropometric analysis were also performed. Secondarily, the relation between food aversion and weight loss was also obtained.

resultsFinal analysis was based on 154 patients (104 LGBP and 50 LSG). The overall mean time between surgery and questionnaire was 10 ± 6.7 months. Most of the patients (87.6 %) experienced some taste/smell change. There were no differences between procedures for any change, taste or smell change. More patients submitted to LGBP referred that food smelled different (51.9 vs 34 % for the LSG group; p = 0.040). Higher %EWL was observed for patients presenting food aversion (73.3 ± 19.7 vs 65.8 ± 19.4 % for those without aversion; p = 0.046). Based on type of surgery, the LGBP group had the same trend (%EWL of 78.2 ± 17.3 vs 70.4 ± 18.6 % for those without aversion; p = 0.044).

conclusionThe majority of patients presented taste and olfactory changes soon after surgery independently of type of procedure. Patients submitted to LGBP referred more often a different smell in food. Higher %EWL was observed in patients presenting any food aversion, especially in the LGBP group.
