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

Flowering in day-neutral tobacco (Nicotiana tabacum) cultivars requires the photoperiod-dependent expression of FLOWERING LOCUS T (FT)-like floral activators, which compete with FT-like inhibitors to interact with FD proteins and induce the switch from vegetative to reproductive growth. In the short-day (SD) cultivar Maryland Mammoth (MM), vegetative growth persists under long-day (LD) conditions, generating unusually tall plants. We found that overexpression of the major LD floral inducer (NtFT5) from the day-neutral cultivar Hicks induces flowering in MM plants under LD conditions. However, a 2-bp deletion near the end of the endogenous NtFT5
