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

backgroundWhile general population studies have demonstrated a relationship between cigarette smoking and weight loss, this association is not well established among the bariatric patient population. Given that bariatric patients are inherently weight-concerned, understanding the effects of smoking on postoperative weight loss is essential. We examined the association of preoperative smoking, postoperative smoking and changes in smoking status with weight loss after bariatric surgery. In addition, we examined the association of changes in smoking status with subjective indices of patient satisfaction while controlling for weight loss.

methodsRetrospective chart review of patients who underwent Sleeve Gastrectomy or Roux-en-Y Gastric Bypass for weight loss at a single institution between August 2000 and November 2017. Additional follow up was obtained by telephone survey. Statistical analysis utilized multivariate logistical regressions.

resultsOur study included 512 patients. Majority were female (n = 390, 76.2%) and underwent laparoscopic Roux-en-Y gastric bypass (n = 362, 70.7%). Average age was 46.8 years and average follow up was 6.99 years. Preoperative, postoperative and changes in smoking status were not significantly associated with weight loss. Former smokers were significantly more likely to report postoperative satisfaction with self-overall OR 10.62 (p < 0.01), satisfaction with postoperative outcomes OR 4.18 (p = 0.02), and improvement in quality of life OR 4.05 (p = 0.04) compared to continued smokers independent of weight loss. No difference in rates of satisfaction were found between former smokers and never smokers. Smoking cessation and weight loss were independently predictive of positive responses to these satisfaction indices.

conclusionsWe found no association between preoperative smoking, postoperative smoking or changes in smoking status with postoperative weight loss. Smoking cessation was associated with patient satisfaction and improvement in quality of life compared to continued smokers. Smoking cessation and postoperative weight loss were independently predictive of increased patient satisfaction.
