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

backgroundChronotype defines an organism's biological preference for timing of activity and sleep. Being a morning chronotype (i.e., tending to wake up early and go to bed earlier at night) is associated with protection against chronic musculoskeletal pain and headaches, but the relationship between chronotype and neuropathic pain sensitivity remains unclear.

objectivesThe aim of this pilot study was to explore the relationship among chronotype, neuropathic pain sensitivity, and pain interference in patients with chronic neuropathic pain disorders. STUDY

designThis was a prospective, observational, single-center, cross-sectional study.

settingPatients were recruited from pain management clinics.

methodsThe Morningness-Eveningness Questionnaire (MEQ) was used to evaluate circadian typology. Linear mixed-effects models, principal component analysis, and principal component regression were used to determine the predictors of pain intensity and pain interference evaluated by the Numeric Rating Scale (NRS) and Patient-Reported Outcomes Measurement Information System Pain Interference (PROMIS-PI) scores, respectively.

resultsWe analyzed 38 adults who had at least one documented chronic neuropathic pain diagnosis. Morning-chronotype patients reported higher NRS scores over time and lower PROMIS-PI t-scores than did intermediate chronotypes. MEQ, depression, risk of sleep apnea, sleep quality, and body mass index (BMI) were all significant independent predictors of average NRS scores and PROMIS-PI t-scores. LIMITATIONS: The population was small and homogeneously white, with an average age of 57 years. However, this population was representative of our pain clinic.

conclusionsMorning chronotypes are more sensitive to chronic neuropathic pain, reporting higher pain scores than do intermediate chronotypes. However, in this study, morning chronotypes were more resistant to neuropathic pain interference, suggesting that they may experience less disturbance of their physical, mental, and social activities than intermediate chronotypes. Further, larger studies are needed.
