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
introductionCalcium and/or vitamin D deficiency can occur after Roux-en-Y gastric bypass (RYGBP) because of impaired absorption, resulting in secondary hyperparathyroidism and increased risk of reduced bone mineral density (BMD).
objectiveThe objective of this study is to assess nutritional status, body composition, and bone health in women after RYGBP.
methodTwenty-five premenopausal women who had undergone RYGBP (test group) and 33 women matched for age and body mass index who had not undergone surgery (control group) participated. Test group received 250 mg of calcium for day. Anthropometric, dietary, laboratory, body composition, and BMD (X-ray absorptiometry) analyses were performed.
resultsNo differences were found between the groups in waist circumference, fat or lean mass, BMD, or dietary calcium intake, although calcium intake was low in both groups. The test group had better results for complete blood count, total cholesterol, low-density lipoprotein, and triglycerides. The mean parathyroid hormone was higher (p = 0.005) in the test group, although still within normal limits. Plasma levels of 25-hydroxyvitamin D were low in groups but did not differ between them (p = 0.075). Vitamin D concentrations were lower in women with longer time since surgery. The test group had lower intake of energy, protein, lipids, polyunsaturated fatty acids, fiber, phosphorus, and iron than the control group.
conclusionElevation of parathyroid hormone, low dietary calcium intake, and vitamin D plasma insufficiency without BMD reduction occurred after RYGBP. Patients who underwent RYGBP had adequate lipid profiles but inadequate intake protein, polyunsaturated fatty acids, fiber, and iron. Vitamin D deficiency may occur in the late postoperative period.
