Prevalence of Chronic Kidney Disease in Morbidly Obese Japanese and the Impact of Bariatric Surgery on Disease Progression.
Article in Obesity surgery, 2018. 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
backgroundThe prevalence of chronic kidney disease (CKD) among Japanese morbidly obese patients undergoing bariatric surgery and the impact of bariatric surgery on their renal function has not previously been investigated.
objectivesThe aims were to assess the prevalence of CKD patients who underwent bariatric surgery in our institution and to elucidate the impact of bariatric surgery on their kidney function as measured by the estimated glomerular filtration rate by Cystatin-C (eGFRcys).
settingThe setting of the study was in a single private hospital.
methodsTwo hundred fifty-four consecutive Japanese patients who underwent bariatric surgery were retrospectively analyzed to elucidate the prevalence of CKD. The eGFRcys was calculated to assess the change in the kidney function for 1 year after surgery.
resultsThe preoperative prevalence of CKD was as follows: G1, 45.3%; G2, 47.2%; G3, 6.5%; and G4, 0.9%. The eGFRcys values before and after surgery were compared; the G1 and G2 patients showed significantly improved eGFRcys values after surgery (G1 101 [94-108] vs 114 [103-127]; G2 79 [74-84] vs 97 [87-104] ml/min/1.73 m
conclusionBariatric surgery resulted in the significant improvement in the eGFRcys values of Japanese patients with morbid obesity, particularly those with pre-CKD (eGFRcys ≥ 60 ml/min/1.73 m
