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

objectiveTo examine a large UK cohort of patients with postural tachycardia syndrome (PoTS), to compare demographic characteristics, symptoms and treatment of PoTS at one centre compared to the largest patient group PoTS UK and to verify if their functional limitation is similar to patients with chronic fatigue syndrome (CFS).

designA cross-sectional study assessed the frequency of symptoms and their associated variables. PATIENTS AND

settingTwo PoTS cohorts were: (1) recruited via PoTS UK, (2) diagnosed at Newcastle Hospitals National Health Service (NHS) Foundation Trust 2009-2012. Patients with PoTS were then compared to a matched cohort with CFS.

main outcome measuresPatients' detailed demographics, time to diagnosis, education, disability, medications, comorbidity and precipitants. Symptom assessment tools captured, Fatigue Impact Scale, Epworth Sleepiness Scale, Orthostatic Grading Scale (OGS), Hospital Anxiety and Depression Scale, Health Assessment Questionnaire, Cognitive Failures Questionnaire.

results136 patients with PoTS participated (84 members of PoTS UK (170 cohort; 50% return) and 52 (87 cohort; 60%) from Newcastle Clinics). The PoTS UK population was significantly younger than the clinic patients, with significantly fewer men (p=0.005). Over 60% had a university or postgraduate degree. Significantly more of the PoTS UK cohort were working, with hours worked being significantly higher (p=0.001). Time to diagnosis was significantly longer in the PoTS UK cohort (p=0.04). Symptom severity was comparable between cohorts. The PoTS total group was compared with a matched CFS cohort; despite comparable levels of fatigue and sleepiness, autonomic symptom burden (OGS) was statistically significantly higher. The most common treatment regime included β-blockers. Overall, 21 treatment combinations were described. Up to 1/3 were taking no treatment.

conclusionsPatients with PoTS are predominantly women, young, well educated and have significant and debilitating symptoms that impact significantly on quality of life. Despite this, there is no consistent treatment.
