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

The porcelain gallbladder condition describes gallbladder calcification. While gallbladder calcification is believed to increase the risk of developing gallbladder cancer, recent reports have shown that the malignancy risk is much lower than previously reported. Symptomatic patients with porcelain gallbladder should be recommended for cholecystectomy, but the management of asymptomatic patients is debatable. Based on recent evidence, prophylactic cholecystectomy is not routinely recommended in all patients with porcelain gallbladder. From the assessment of the current literature, there are three essential factors in the management of patients with porcelain gallbladder: (1) symptoms or complications of gallbladder disease, (2) calcification pattern and (3) patient age and comorbidities. Patients who do not undergo cholecystectomy should be educated about the symptoms of gallbladder diseases, and a thorough discussion is essential between patients and clinicians.
