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
purposeAfter bariatric surgery (BS) a significant minority of patients do not reach successful weight loss or tend to regain weight. In recent years, interest for the psychological factors that predict post-surgical weight loss has increased with the objective of developing interventions aimed to ameliorate post-surgical outcomes. In the present study, predictive models of successful or poor weight loss 12 months after BS were investigated considering pre-surgery level of psychopathological symptoms, dysfunctional eating behaviors and trait impulsivity at baseline (pre-surgery).
methodsSixty-nine patients with morbid obesity canditates for laparoscopic sleeve gastrectomy were assessed regarding metabolic and psychological dimensions. Successful post-surgery weight loss was defined as losing at least 50% of excess body weight (%EWL).
resultsLogistic models adjusted for patient sex, age and presence of metabolic diseases showed that the baseline presence of intense psychopathological symptoms and low attentional impulsivity predict poor %EWL (< 50%), as assessed 12-month post-surgery.
conclusionsThe present findings suggest that intensity of general psychopathology and impulsivity, among other psychological factors, might affect post-surgery %EWL. Conducting adequate psychological assessment at baseline of patients candidates for BS seems to be crucial to orient specific therapeutic interventions. LEVEL OF EVIDENCE: Level III, case-control analytic study.
