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

The superantigen Staphylococcal enterotoxin A (SEA) conjugated to tumour-specific monoclonal antibodies (mAb) directs T cells to lyse tumour cells in the absence of major histocompatibility complex (MHC) class II. In contrast, the conjugate bound to MHC class II-negative tumour cells did not activate resting T cells to proliferate. The SEA-C215 mAb conjugate, when presented on the CA215 antigen-expressing Colo205 cells, required either signalling with CD28 mAb or CHO cells expressing the natural CD28 ligand, B7, to activate the T cells. The CD28/B7 co-stimulatory effect was further enhanced when the B7 and the tumour antigen were present on the same cell, decreasing the superantigen amount required for activation with a factor of 10(4). No influence of B7 was seen when the single CA215 or double CA215/B7 transfectants were used as targets for superantigen conjugate-dependent cytotoxicity. This suggests that the low affinity T-cell receptor (TcR) interaction of superantigen in the absence of MHC class II antigens is sufficient for induction of cytotoxicity but requires additional CD28/B7 signalling to result in proliferation of resting T cells.
