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

We report two cases of patients complaining of lumbar back pain of unknown etiology which were finally diagnosed as multiple myeloma. The first case was a woman in her 80s with a chief complaint of lumbar back pain. The second case was a male in his 70s. He also consulted our institution because his pain did not subside despite receiving increased doses of oral medication and nerve blocks from his previous doctor. Both patients presented with compression fractures on plain radiography, and additionally with cytopenia, hyperproteinemia, and hypoalbuminemia in blood tests. Further tests were conducted due to suspected multiple myeloma, revealing a punched-out legion in the skull and elevated levels of β2 microglobulin and Immunoglobulin G. Subsequently, both patients were transferred to the hematology department. In these two cases, we had predicted the presence of multiple myeloma from the results of initial testing and subsequently successfully provided definitive diagnoses following additional examinations.
