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 differentiation potential of the human retinoblastoma cell lines Y-79 and WERI-Rb1 was evaluated in vitro for up to 120 days in a matrix system and in rotary suspension for 30 days. Matrix cultures were grown with 10% fetal calf serum (FCS), with and without differentiation-promoting agents. The latter were applied for a total of 5-45 days (usually 30 days) and included 7S nerve growth factor, dibutyryl cyclic AMP, sodium butyrate, retinoic acid, hydrocortisone, and ascorbic acid. Fully defined, serum-free medium and medium containing 5 or 15% FCS were also used for matrix cultures, and medium with 5 or 10% FCS for suspension cultures. By immunoperoxidase (performed on matrix cultures, both untreated and treated for 30 days with differentiation-promoting agents), the cells of both lines were positive for neuron-specific enolase (NSE), microtubule-associated protein 2 (MAP2), class III beta-tubulin (human h beta 4) isotype, and synaptophysin. In addition, the WERI-Rb1 cells expressed 200 kd neurofilament protein (NFP-H) and retinal S-antigen. Both lines were invariably negative for glial fibrillary acidic (GFA) protein, myelin-associated glycoprotein, myelin basic protein, the epitope recognized by the Leu-7 monoclonal antibody, opsin, and hydroxy-indole-O-methyltransferase. In the Y-79 line the presence of NSE and the absence of NF proteins-H, -M and -L, of GFA protein, and of retinal S-antigen were confirmed biochemically. No differentiated features were found by electron microscopy in either line. Thus, in the matrix system employed, both lines exhibited solely a potential for neuroblastic differentiation, which was more advanced in the WERI-Rb1 line, as reflected by the antigenic expression of NFP-H and of retinal S-antigen.
