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

Five guava (Psidium guajava L.) genotypes, Punjab Pink, Hisar Surkha, Black guava, Shweta, and Pant Prabhat were studied for their pulp colour development at four stages: S1, when seed ball started developing colour; S2, when pulp started developing pink colour; S3, when uniform pink colour developed in pulp and seed ball; and S4, mature ripe. The two stages namely S2 and S3 in pink pulped guava genotypes had shown marked changes in pigment content and Hunter colour L*, a*, b* values. Hence, these stages are appropriate to study the expression of genes related to pulp colour. Out of three colour indices i.e., CI-1[1000 x a*/ (L* x b*)]; CI-2 [1000 x a*/ L*]; and CI-3 [1000 x b*/L*], the CI-2 had significantly higher correlation values for total anthocyanin (0.786) and lycopene (0.418) content. It also had higher correlation value for total carotenoid content (0.263) as compared to CI-1 and CI-3. The CI-2 values clearly distinguished between purple, pink and white pulped guava. Hence, it can be used for colour measurement and to decide the criteria for raw material (guava) selection for processing industry to develop safe products which are free from artificial colourants for consumers.
