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

backgroundHepatitis C virus infection is the most commonly reported bloodborne infection in Pakistan. Frequent blood transfusions in β-thalassemia patients expose them to a high risk of HCV infection. The purpose of this paper is to summarise the current data on the prevalence of HCV infection in β-thalassemia patients in Pakistan by using a systematic review and meta-analysis.

methodsPubMed, EMBASE, Web of Sciences, the Cochrane Library, Directory of Open Access Journal and local databases were systematically searched for studies published between January 1st, 1995 and May 31st, 2019. Meta-analysis was performed using the DerSimonian and Laird random-effects models with inverse variance weighting. The presence of publication bias was tested by Egger test, and the methodological quality of each included article was evaluated by the STROBE.

resultsWe identified a total of 229 potential studies, of which 27 studies were finally considered in the meta-analysis. The pooled prevalence of HCV in β-thalassemia patients in Pakistan was 36.21% (95% CI: 28.98-43.75%) based on 5789 β-thalassemia patients, but there was considerable heterogeneity. Meta-analysis estimated the HCV prevalence among the β-thalassemia patients at 45.98% (95% CI: 38.15-53.90%) in Punjab, 31.81% (95% CI: 20.27-44.59%) in Sindh, and 28.04% (95% CI: 13.58-45.26%) in Khyber Pakhtunkhwa. Meta-regression analysis showed that geographical location was a key source of heterogeneity.

conclusionsThe pooled prevalence of HCV in β-thalassemia patients in Pakistan was more than one in three, and higher than in neighbouring countries. It varies regionally within the country. With the use of standard prevention procedures during blood transfusion, the risk of HCV transmission in β-thalassemia patients could be controlled and the prevalence of HCV in β-thalassemia patients reduced.
