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.
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
Freshwater lakes in Jammu and Kashmir face escalating ecological degradation due to anthropogenic pressures, particularly heavy metal contamination, posing unresolved risks to food safety and ecosystem integrity. This study investigated heavy metal accumulation in water chestnut (Trapa natans) across four major water bodies, i.e., Dal Lake, Hokersar Wetland, Manasbal Lake, and Wular Lake. Water, sediment, and plant tissues (root, shoot, fruit) were collected and analyzed for eight heavy metals (Cd, Cr, Cu, Co, Fe, Mn, Ni, Zn) using ICP-OES along with physicochemical profiling. Results indicated a distinct spatial gradient, with Dal Lake exhibiting the highest pollution load. Roots exhibited the highest heavy metal concentrations among plant tissues, with Fe (322.50 mg kg
