Weight Loss Following Orthognathic Surgery: a Descriptive Prospective Cohort Study.
Article in Journal of oral & maxillofacial research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Objectives: The purpose of this prospective cohort study was to assess weight loss in kg following orthognathic surgery focusing on gender, type of surgery, employment, and living arrangements, as effect modifiers. Material and Methods: Patient weights were measured at four points during their trajectory; two weeks preoperatively, week one, week three, and week eight postoperatively. Additionally, the registered nurse collected the following information: (1) patient age; (2) gender; (3) status of employment; (4) type of surgery; and (5) living arrangement. Results: Mean weight loss of 3.35 kg (95% CI [confidence interval] = 3.07 to 3.62, P < 0.001), 3.56 kg (95% CI = 3.23 to 3.89, P < 0.001), and 2.79 kg (95% CI = 2.36 to 3.21, P < 0.001) for week 1, 3 and 8. Higher weight loss was observed in males 3.81 kg (95% CI = 3.31 to 4.31) compared with females 3 kg (95% CI = 2.71 to 3.29) at week 1 (P = 0.01). Highest weight loss following bimaxillary surgery was observed at week 1 (P = 0.00) and week 8 (P = 0.04). Conclusions: Postoperative proportional weight loss is observed in all patients undergoing orthognathic surgery. Being male and having bimaxillary surgery predicts for a higher weight loss. Patients who had bimaxillary procedures showed greater weight loss compared to those who had a single jaw procedure, possibly due to longer surgery times, increased facial swelling and restricted mouth opening. Interestingly, living arrangements seemed to have an effect on weight loss at week 3, suggesting that social support may influence nutritional status.
