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

backgroundPeriodontal disease has been associated with a number of systemic diseases. A high prevalence of periodontitis among individuals with chronic kidney diseases and end-stage renal disease has been reported. However, no association between periodontal diseases and glomerulonephritis has previously been investigated.

objectiveThe aim of this study was to assess the severity and possible role of periodontitis in a group of patients with unknown primary glomerulonephritis.

methodsTen patients with unknown primary glomerulonephritis, and who had a renal biopsy with stable renal function and serum creatinine <1.6 mg/dL, were recruited. Severity of the periodontal disease was clinically measured with plaque index (PI), gingival index (GI), and periodontal pocket depth (PD). The subjects received appropriate dental treatments where indicated. The patients were also put on angiotensin-converting enzyme inhibitor or angiotensin receptor blockers for controlling blood pressure and proteinuria. Six months following appropriate periodontal treatment, renal function, degree of proteinuria, and level of C-reactive protein (CRP) were measured in each individual.

resultsThe median age of the patients was 30 (15.8) years. The median urine protein excretion was lower following the periodontal therapy (P=008). Prior to the dental and/or periodontal therapies, the median PI, PD, and GI were 57.5%, 4.3, and 1.1, respectively. The majority of the patients had advanced periodontal disease. In four patients, +2/+3 CRP turned negative after periodontal treatment.

conclusionsThe present study revealed that a causative link might exist between periodontal disease and glomerulonephritis.
