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

objectivesNeck pain commonly accompanies recurrent headaches such as migraine, tension-type and cervicogenic headache. Neck pain may be part of the headache symptom complex or a local source. Patients commonly seek neck treatment to alleviate headache, but this is only indicated when cervical musculoskeletal dysfunction is the source of pain. Clinical presentation of reduced cervical extension, painful cervical joint dysfunction and impaired muscle function collectively has been shown to identify cervicogenic headache among patients with recurrent headaches. The pattern's validity has not been tested against the 'gold standard' of controlled diagnostic blocks. This study assessed the validity of this pattern of cervical musculoskeletal signs to identify a cervical source of headache and neck pain, against controlled diagnostic blocks, in patients with headache and neck pain.

designProspective concurrent validity study that employed a diagnostic model building approach to analysis.

settingHospital-based multidisciplinary outpatient clinic in Joliet, Illinois.

participantsA convenience sample of participants who presented to a headache clinic with recurrent headaches associated with neck pain. Sixty participants were enrolled and thirty were included in the analysis. OUTCOME MEASURES: Participants underwent a clinical examination consisting of relevant tests of cervical musculoskeletal dysfunction. Controlled diagnostic blocks of C2/C3-C3/C4 established a cervical source of neck pain. Penalised logistic regression identified clinical signs to be included in a diagnostic model that best predicted participants' responses to diagnostic blocks.

resultsTen of thirty participants responded to diagnostic blocks. The full pattern of cervical musculoskeletal signs best predicted participants' responses (expected prediction error = 0.57) and accounted for 65% of the variance in responses.

conclusionsThis study confirmed the validity of the musculoskeletal pattern to identify a cervical source of headache and neck pain. Adopting this criterion pattern may strengthen cervicogenic headache diagnosis and inform differential diagnosis of neck pain accompanying migraine and tension-type headache.
