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

introductionAlthough bariatric surgery promotes dietary changes, many questions regarding their effect on weight loss remain unanswered.

objectiveThe aim of this study was to evaluate changes in dietary intake and predictive factors of obesity remission in the first 12 months after RYGB.

methodsFifty-one patients (mean 39.34 ± 9.38 years, 68.7% women) who underwent RYGB were included in this study. Dietary intake was evaluated through a 24-h dietary recall and subsequently classified by NOVA, macronutrients and calories. The predictive factors for obesity remission within 12 months after RYGB were evaluated by Cox regression.

resultsAt baseline, 62.7% of the patients presented severe obesity; mean excess weight loss was greater than 80% after 1 year of surgery and about 70% of the patients were no longer diagnosed with obesity. An increase in percentage of calories from protein was observed at 3 and 12 months after surgery. The caloric contribution of ultra-processed foods was low at 3 months after surgery while that of unprocessed or minimally processed foods was high at 3 and 12 months after surgery. From the Cox regression analysis, preoperative BMI (HR, 0.78; 95% CI, 0.69-0.88) and age (HR, 0.94; 95% CI, 0.89-0.99) showed an inverse association with obesity remission. Also, Δ protein (at 3 months-baseline) showed a positive association with obesity remission (HR, 1.06; 95% CI, 1.01-1.12).

conclusionLower preoperative BMI, lower age, and higher protein intake at 3 months after surgery may favor remission of obesity in up to 12 months compared with baseline.
