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

backgroundSpinal metastasis is considered to have a worse prognosis in lung cancer than in other cancers, but recent clinical studies report improved overall survival of lung cancer. We compared the postoperative prognoses of vertebral metastatic tumors from lung with other types of cancer.

methodsFrom 2011 to 2015, 31 Japanese patients (mean age 73 years, range 55-88 years; 19 males, 12 females) underwent surgery for spinal metastasis at our center. We observed patients retrospectively in March 2016, dividing them into groups by cancer type: lung (LK group, n = 10); prostate, breast, or thyroid (PB group, n = 12); and other (OT group, n = 9). We compared survival and revised Tokuhashi score, which provides a basis for choosing a treatment course. Neurologic status was graded before and after surgery using the Frankel system.

resultsMean follow-up was 16.5 months (range 1-62 months). Only seven of 31 patients (22.6%) were alive at final follow-up. Frankel grade significantly improved postoperatively only in the LK (P = 0.01) and PB (P = 0.048) groups. Revised Tokuhashi score differed across groups (P < 0.0001), and was significantly lower in the LK group than in the PB group (P = 0.00) and OT group (P = 0.02). Postoperative survival was significantly shorter in the LK group than in the PB group (P = 0.01) but did not differ between the LK and OT groups.

conclusionsThe revised Tokuhashi score may underestimate the survival of lung cancer patients, who may derive the same benefit from surgical intervention as those with vertebral metastasis from other cancer types.
