Cost, health impacts and cost effectiveness of iceless refrigeration in India's last-mile vaccine cold chain delivery.
Article in Transactions of the Royal Society of Tropical Medicine and Hygiene, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundCompared with ice-based vaccine carriers (IBVCs), iceless vaccine carrier (ILVC) last-mile delivery could optimize vaccine effectiveness by reducing spoilage. We estimated ILVC-associated spoilage costs averted and cost effectiveness.
methodsIBVC vaccine spoilage costs were estimated for six vaccines. ILVC incremental costs were based on yearly ILVC cost over total doses. Cost effectiveness was estimated via Markov modeling of rotavirus vaccine.
resultsThe spoilage cost using IBVCs was US$9 603 294. Using ILVCs, the incremental cost per vaccine dose was US$0.026, the cost-benefit ratio was 0.28, the number of averted disability-adjusted life years was 0.03 per child and there was a saving of US$0.80 per child vaccinated.
conclusionsILVCs may bring cost savings and health gains compared with IBVCs.
