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

A recent systematic review reported very high pooled estimates of blood lead levels (BLLs) for Indian children. Current study aimed at systematically pooling the BLLs of Indian children (aged ≤ 14 years). Further, explore the time trend of BLLs with respect to implementing the ban on the use of Pb-petrol (i.e.2000) and a decade later (2010). Observational studies documenting the BLL in Indian children (aged ≤ 14 years) from PubMed-Medline, Scopus, and Embase digital databases from inception to August 2024 were systematically reviewed. Detailed protocol is available at PROSPERO (ID: CRD42022382835). Pooled mean BLL was estimated using the random-effects model and conventional-
