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

purposeUp to 30-40 % of the major depressive disorder patients do not respond sufficiently to antidepressant treatment. Genetic variations in the serotonin transporter gene have been implicated in modulating treatment response to selective serotonin reuptake inhibitors, and this association is influenced by ethnicity. We investigated the influence of serotonin transporter gene variants 5-HTTLPR and rs25531 in Indian population on fluoxetine response.

methodsOne hundred and two major depressive disorder patients were started on fluoxetine treatment and after 6 weeks, classified as responders (n = 56) and non-responders (n = 46) using Hamilton depression rating scale and genotyped. Fisher's exact test was used to compare genotype frequencies between responders and non-responders. One-way analysis of variance and student t test were used to compare the percentage reduction (week 0-6) in Hamilton depression rating scores between genotype and haplotype groups.

resultsWe observed a significant association between LL genotype of 5-HTTLPR and fluoxetine treatment response (p = 0.0066, OR (95 %) = 4.0 (1.45-11.03)) but not with the functional groups of 5-HTTLPR -rs25531. However, there was a significant difference in percentage reduction in HAM-D scores (week 0-6) between 5-HTTLPR genotypes (LL vs. LS + SS, p = 0.0036; LL vs. LS, p = 0.0109) as well as the functionally grouped haplotypes of 5-HTTLPR -rs25531 (LALA carriers vs. non-carriers of LALA, p = 0.0118; LALA vs. LAS+ LALG, p = 0.0419).

conclusionThe LL genotype and LALA haplotype of SLC6A4 are associated with favorable treatment response to fluoxetine in south Indian major depression patients.
