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

purposeThere are discrepancies between patients' expected weight loss and what is considered achievable after bariatric surgery. This study describes the association between patients' expectations and actual weight loss, 1 and 2 years postoperatively. MATERIALS AND

methodsA prospective observational study was performed. The association between expectations and actual weight loss (% total weight loss) was explored using linear regression analyses, adjusting for baseline demographics, surgery types, and self-esteem (Rosenberg self-esteem scale) and repeated separately per gender. Gender differences in motivations were explored using Chi-square tests.

resultsOf 440 patients at baseline, results on 368 (84%) at 1 year and 341 (78%) patients at 2 years were available. Significant and opposite associations were found when analyzing genders separately. There was a significant negative association between expectations and %TWL in men at 1 year (β - 0.23, p = 0.04) and 2 years postoperatively (β - 0.26, p = 0.03), indicating smaller weight loss for greater expectations. In women, a significant positive association (β 0.24, p < 0.01) was found 2 years postoperatively, indicating greater weight loss for greater expectations. Both genders were mainly motivated by health concerns, but women were also motivated by reduced self-confidence to lose weight.

conclusionsHigher expectations were negatively associated with weight loss in men, but positively in women. This may be due to men being motivated by physical complaints, which improve with lower weight-loss. Women are also driven by reduced self-confidence, which may influence weight loss maintenance behaviors. Higher weight loss goals should not be considered as a contra-indication for surgery, but may be utilized to achieve patients' goals.
