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

key messageA 2-bp insertion in McLecrk1b encoding an L-type lectin receptor-like kinase (L-LecRLK), the candidate gene for the major QTL mfl5.1 for mature fruit length, results in a premature stop codon and causes short fruit in bitter gourd. Fruit length is a key determinant of yield and market class in bitter gourd, yet the causal genes controlling fruit elongation remain largely unknown. In our previous QTL analysis using two inbred accessions with extremely short (HNU004) and moderately long (HNU025) fruits, mfl5.1 showed the largest effect. Here, we applied marker-assisted backcrossing to minimize background effects from additional loci and performed map-based cloning using a large BC
