Pica in Sickle Cell Disease: A Systematic Review and Meta-Analysis.
Review in Anemia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Pica, the persistent ingestion of non-nutritive, non-food substances for ≥ 1 month at a developmentally inappropriate age, is regularly observed but understudied in sickle cell disease (SCD). Its prevalence and risk factors are unclear. This systematic review aims to estimate pica prevalence and synthesize evidence on associated characteristics and correlates in SCD. We searched Embase, MEDLINE ALL, Web of Science, Cochrane CENTRAL, PsycINFO and Google Scholar up to 31 October 2025, for studies reporting original data on the prevalence and characteristics of pica in individuals ≥ 2 years with SCD. Risk of bias was assessed using a modified Newcastle-Ottawa Scale. Meta-analysis of prevalence used random-effects models. Data on substances consumed were pooled. Literature on potential correlates was narratively summarized across biological, psychological and social domains. Ten studies (1585 participants) from North America (
