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

purposeTo evaluate postoperative recurrence, survival and metastasis results and related factors of sacral chordoma.

methodsBetween 1978 and 2013, a total of 171 patients with sacral chordoma were diagnosed at our institution and 162 cases underwent operation. The clinical characteristics, treatment and outcomes of all these patients were reviewed.

resultsThe 3-year recurrence free survival rate was 83.1%. The median recurrence free survival time was 73 ± 7.8 months. Tumor level in sacrum and surgical margin were significant factors influencing recurrence. Recurrence was significant factor influencing metastasis. One hundred and fifty-seven cases were followed up for an average of 55.6 months. 135 cases (86%) survived, 37 cases (23.6%) developed recurrence, and 17 cases (10.8%) developed metastasis. The overall 5- and 10-year survival rate was 88.3% and 59.6%, respectively. Age (p = 0.037) and metastasis (p = 0.001) were significant factors influencing survival. The 3-year recurrence free survival rate was 80.1%. The median recurrence free survival time was 69 ± 12.7 months. Tumor level in sacrum (p = 0.035) and surgical margin (p = 0.009) were significant factors influencing recurrence. Seventeen cases (10.8%) had metastasis. Recurrence (p = 0.016) was significant factors influencing metastasis.

conclusionsSacral chordoma tended to occur in elderly male patients and locate below sacral 3 level. The recurrence rate was high, especially for tumor above sacral 3 level. Wide surgical margin is very important for good local control. The patients with metastasis had poor prognosis.
