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

BACKGROUND/

aimsSleep disorders (SDs) are frequently seen in patients with liver cirrhosis. Polysomnography (PSG), actigraphy, and electroencephalogram (EEG) are the common objective methods to diagnose SDs. The most commonly used subjective methods are the Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale (ESS). We aimed to evaluate the effect of liver transplantation (LTx) on SDs using a combination of objective (PSG and EEG) and subjective (PSQI and ESS) methods. MATERIALS AND

methodsA total of 18 patients with cirrhosis on an LTx waiting list were included in this study. Patient clinical status and biochemical parameters were evaluated. All patients completed the validated Turkish forms of the PSQI and ESS before and 9 months after LTx. All patients underwent EEG and PSG before and 9 months after LTx.

resultsIn total, 18 patients with liver cirrhosis (men: 12; 66.7%, mean age: 53.22±10.43 years) were included in this study. Pretransplant mean PSQI and ESS scores were 8.4±3.11 and 7.28±3.89, respectively; 9-month posttransplant mean PSQI and ESS scores were 4.5±2.8 and 4.72±2.91 (p<0.01), respectively. Before transplantation, metabolic encephalopathy was detected in 6 patients by EEG, whereas metabolic encephalopathy was detected in only 1 patient posttransplant. Posttransplantation PSG sleep duration (all stages) increased relative to pretransplant PSG values. Sleep latency and rapid eye movement latency were found to be reduced compared to the pretransplant values.

conclusionThis pilot study compared SDs in patients with pre- and post-LTx by combining the subjective and objective methods. Significant SD improvements were found at the 9th month.
