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
backgroundObesity and type 2 diabetes mellitus are highly prevalent conditions with a significant public health impact, highlighting the need for effective management strategies. Bariatric surgery is widely recognized for promoting sustained weight loss and high rates of type 2 diabetes mellitus remission.
aimsThis study investigated the preoperative blood glucose response to a very low-calorie diet as a functional predictor of type 2 diabetes mellitus remission following Roux-en-Y gastric bypass.
methods198 participants who followed a very low-calorie diet (600 kcal/day) during the preoperative period were included, with glycemic response monitoring.
resultsComplete remission of type 2 diabetes mellitus occurred in 66.7% of patients. Two years after surgery, patients with blood glucose levels below 143 mg/dL on the second day of the very low-calorie diet had a higher likelihood (over 70%) of achieving complete remission type 2 diabetes mellitus in the late postoperative period.
conclusionsPreoperative capillary blood glucose levels demonstrated good specificity in predicting remissions. These findings reinforce the clinical utility of early glycemic control as a valuable indicator for predicting the success of surgical treatment for type 2 diabetes mellitus.
