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

purposePrevious reports on the outcome of conservative treatment for dropped head syndrome (DHS) are scarce. The purpose of this study was to elucidate the efficacy of conservative treatment for DHS and to identify possible predictive factors relating to the outcome.

methodsAmong 76 DHS patients, conservative treatment (2-3 months collar application, active neck range of motion exercise, and occasional prescription of analgesics) succeeded in 17 patients (22.4%, group S, 4 male, 13 female, mean age 75.9 years). The treatment failed in the remaining 59 patients (group F). Clinical and radiological parameters were compared between the groups. Radiological findings of group S were compared between before treatment and at follow-up.

resultsDuration of disease was 6.6 ± 9.3 months in group S and 20.0 ± 27.6 months in group F. C2-7 angle (degree), the incidence of anterior slippage of the vertebra (%), reducibility (%), and upper thoracic kyphosis angle (degree) in group S/F were - 19.2 ± 17.5/- 34.6 ± 26.6, 23.5/62.7, 100/52, and 6.7 ± 8.6/17.9 ± 13.7, respectively. C2-7 angles were - 19.2 ± 17.5 degrees at pre-treatment and 10.2 ± 20.7 degrees at follow-up. These differences were statistically significant.

conclusionsThe present study indicated that conservative treatment was successful in 22% of DHS patients, with improvement in their cervical kyphotic alignment. Shorter duration of disease, relatively smaller cervical kyphosis without anterior slippage of the vertebra, reducibility, and abundant compensation at the upper thoracic region were good indications for the success of conservative treatment.
