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

backgroundThe outcome of leishmaniasis is an interplay between Leishamania and the host. Identifying contributory host genetic factors is complicated by the variability in phenotype, ethnicity and parasite species. Leishmaniasis is caused exclusively by L. donovani in Sri Lanka with localized cutaneous leishmaniasis (LCL) being the predominant form. We report here an association study of human leucocyte antigen (HLA) class I and II genes with LCL in Sri Lanka, the first on HLA associations in cutaneous leishmaniasis in a South Asian population.

methodsAn existing DNA repository of 200 each of patients and controls was typed for HLA-DQ by PCR-SSP. Next generation sequencing-based typing for HLA-A, HLA-B and HLA-DRB1 alleles was done in a subset of 280 samples. Association tests were performed on 28,489 genotyped and imputed SNPs spanning a region of 1.4 Mb across the HLA genes. To compare our results with similar studies, we carried out a systematic review to document all HLA associations reported to-date for cutaneous and muco-cutaneous leishmaniasis.

resultsDRB1*04 DQB1*02 (P = 0.03; Pc = 0.09), DRB1*07 DQB1*02 (P = 0.03; Pc = 0.09) haplotypes were absent in patients. B*07 (P = 0.007; Pc = 0.13; OR = 0.36; 95 % CI = 0.17-0.77) allele and DRB1*15 DQB1*06 (P = 0.00; Pc < 0.01; OR = 0.3; 95 % CI = 0.2-.0.6) haplotype were over represented in controls and DRB1*15 (P = 0.002; Pc = 0.01) allele was over represented in patients. Two SNPs (rs281864595/rs1050517) in the antigen recognition region of HLA-B, comprised a haplotype more frequent in controls (P = 0.04). The alleles identified by the systematic review to predispose or to protect from cutaneous/mucocutaneous leishmaniasis remained highly heterogeneous in different populations studied.

conclusionsOur preliminary findings suggest a role for some class I and class II HLA genes in determining predisposition to LCL in this population which should be corroborated with further studies. The systematic review reiterates this need, as the purported susceptibility or protection gained by certain HLA alleles or haplotypes has rarely been independently verified.
