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: About 70-90% of Parkinson's disease (PD) patients have olfactory deficits which is considered as pre-motor symptom of PD. Lewy bodies have been demonstrated in the olfactory bulb (OB) in PD. Objective: To assess the OB volume (OBV), olfactory sulcus depth (OSD) in PD and compare with progressive supranuclear palsy (PSP), multiple system atrophy (MSA) and vascular parkinsonism (VP) patients and determine the cut-off volume of OB that will aid in the diagnosis of PD. Methods: This was a cross-sectional, hospital based, single-center study. Forty PD, 20 PSP, 10 MSA, 10 VP patients and 30 controls were recruited. OBV and OSD was assessed using 3-T magnetic resonance imaging (MRI) brain. Olfaction was tested using Indian Smell Identification test (INSIT). Results: The mean total OBV in PD was 113.3 ± 79.2 mm Conclusion: OBV is reduced in PD patients as compared to PSP, MSA, VP patients and controls. OBV estimation by MRI adds to the armamentarium in the diagnosis of PD.
