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

backgroundThe study on transcranial sonocraphy (TCS) as a diagnostic test for Parkinson's disease (PD) has been neglected in some hospitals. The current study was conducted as the first study to investigate the utility of TCS for diagnosis of PD and its ability to distinguish PD from essential tremor (ET) in an Iranian population. MATERIALS AND

methodsTCS of substantia nigra (SN) was performed on 50 PD, 48 ET, and 50 healthy controls by two blinded investigators.

resultsBilateral SN margin over 0.20 cm(2) was found in 39 (90%) and 7 (15%) in PD and ET patients, respectively. Furthermore, 4 (8%) of healthy control displayed this particular echo feature as well (false positives). SN hyperechogenicity ≥0.20 cm(2) was considered as a cut-off point to detected PD. Accordingly, TCS proved 90% (95% confidence interval [CI]: 77.85-97.35) sensitive and 92% (95% CI: 80.75-97.73)specific for the detection of PD by visualizing the SN.

conclusionSN hyperechogenicity ≥20 cm(2) is a specific feature of PD. Since, the symptoms of PD and ET might be overlapping; this method seems to be reliable to confirm PD diagnosis in doubtful clinical cases. Further studies in years to come are warranted to shed light on standardized data for Iranian to enhance the validity of TCS.
