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

Replication-competent propagation-deficient virus vectors based on the transmissible gastroenteritis coronavirus (TGEV) genome that are deficient in the essential E gene have been developed by complementation within E(+) packaging cell lines. Cell lines expressing the TGEV E protein were established using the noncytopathic Sindbis virus replicon pSINrep21. In addition, cell lines stably expressing the E gene under the CMV promoter have been developed. The Sindbis replicon vector and the ectopic TGEV E protein did not interfere with the rescue of infectious TGEV from full-length cDNA. Recombinant TGEV deficient in the nonessential 3a and 3b genes and the essential E gene (rTGEV-Delta3abDeltaE) was successfully rescued in these cell lines. rTGEV-Delta3abDeltaE reached high titers (10(7) PFU/ml) in baby hamster kidney cells expressing porcine aminopeptidase N (BHK-pAPN), the cellular receptor for TGEV, using Sindbis replicon and reached titers up to 5 x 10(5) PFU/ml in cells stably expressing E protein under the control of the CMV promoter. The virus titers were proportional to the E protein expression level. The rTGEV-Delta3abDeltaE virions produced in the packaging cell line showed the same morphology and stability under different pHs and temperatures as virus derived from the full-length rTGEV genome, although a delay in virus assembly was observed by electron microscopy and virus titration in the complementation system in relation to the wild-type virus. These viruses were stably grown for >10 passages in the E(+) packaging cell lines. The availability of packaging cell lines will significantly facilitate the production of safe TGEV-derived vectors for vaccination and possibly gene therapy.
