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 AND

objectivesStiff person syndrome spectrum disorder (SPSD) is a rare autoimmune disorder characterized by progressive muscle stiffness and painful spasms with an estimated prevalence of 1-2 cases per million people. Population-based epidemiologic studies are lacking because of both poor patient capture and the lack of standardized diagnostic criteria. Objectives of this study were to describe the incidence and prevalence of SPSD within the University of Colorado Health (UCH) system and apply previously proposed published criteria for SPSD within this population.

methodsWe queried Health Data Compass, an electronic health data repository for a large academic health care system, from 2012 through 2022 for all patients older than 18 years with

resultsTwo hundred and seventy-three patients met the initial inclusion criteria using DISCUSSION: We describe a prevalence of SPSD of 2.11 per 100,000 persons in our UCH cohort. Prevalence estimates differed depending on which clinical diagnostic criteria were applied and whether possible SPSD cases were included. Using the most stringent criteria for diagnosis, we report a prevalence of 1.36 per 100,000 persons. While our study uniquely captures many US demographic groups, limitations remain because this is a retrospective review of a single system. Additional studies are needed to determine whether these results are representative of a national or global population.
