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

1. Fast-twitch skeletal muscle fibres were enzymatically dissociated from adult mouse flexor digitorum brevis (FDB) muscles and maintained in culture without or with chronic low frequency stimulation (one 5 s train of 5 Hz pulses per minute) for up to 6 days. Single fibre reverse transcriptase-polymerase chain reaction was conducted to coamplify beta-myosin heavy chain (beta-MHC) and alpha-skeletal actin mRNA from the same fibre. 2. Chronic low frequency electrical stimulation of FDB fibres in culture increased the level of mRNA for beta-MHC. In unstimulated fibres there was a slight decline in the beta-MHC mRNA level. As an internal control there was no increase in the level of mRNA for alpha-actin in the identical individual stimulated or unstimulated fibres. 3. Neither the percentage of fibres exhibiting beta-MHC protein nor the Ca2+ transients recorded from individual fibres subjected to the same pattern of stimulation showed any difference between stimulated and unstimulated fibres over the period in culture. 4. This system provides a convenient in vitro model system for studying activity-dependent control of fibre type-specific gene expression in adult skeletal muscle fibres in culture.
