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

Human parainfluenza virus type 1 (HPIV1) is a significant cause of pediatric respiratory disease in the upper and lower airways. An in vitro model of human ciliated airway epithelium (HAE), a useful tool for studying respiratory virus-host interactions, was used in this study to show that HPIV1 selectively infects ciliated cells within the HAE and that progeny virus is released from the apical surface with little apparent gross cytopathology. In HAE, type I interferon (IFN) is induced following infection with an HPIV1 mutant expressing defective C proteins with an F170S amino acid substitution, rHPIV1-C(F170S), but not following infection with wild-type HPIV1. IFN induction coincided with a 100- to 1,000-fold reduction in virus titer, supporting the hypothesis that the HPIV1 C proteins are critical for the inhibition of the innate immune response. Two recently characterized live attenuated HPIV1 vaccine candidates expressing mutant C proteins were also evaluated in HAE. The vaccine candidates, rHPIV1-C(R84G/Delta170)HN(T553A)L(Y942A) and rHPIV1-C(R84G/Delta170)HN(T553A)L(Delta1710-11), which contain temperature-sensitive (ts) attenuating (att) and non-ts att mutations, were highly restricted in growth in HAE at permissive (32 degrees C) and restrictive (37 degrees C) temperatures. The viruses grew slightly better at 37 degrees C than at 32 degrees C, and rHPIV1-C(R84G/Delta170)HN(T553A)L(Y942A) was less attenuated than rHPIV1-C(R84G/Delta170)HN(T553A)L(Delta1710-11). The level of replication in HAE correlated with that previously observed for African green monkeys, suggesting that the HAE model has potential as a tool for the preclinical evaluation of HPIV1 vaccines, although how these in vitro data will correlate with vaccine virus replication in seronegative human subjects remains to be seen.
