Mutations in intron 1 and intron 22 inversion negative haemophilia A patients from Western India.
Trial report in PloS one, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Despite increased awareness and diagnostic facilities, 70-80% of the haemophilia A (HA) patients still remain undiagnosed in India. Very little data is available on prevalent mutations in HA from this country. We report fifty mutations in seventy one Indian HA patients, of which twenty were novel. Ten novel missense mutations [p.Leu11Pro (p.Leu-8Pro), p.Tyr155Ser (p.Tyr136Ser), p.Ile405Thr (p.Ile386Thr), p.Gly582Val (p.Gly563Val) p.Thr696Ile (p.Thr677Ile), p.Tyr737Cys (p.Tyr718Cys), p.Pro1999Arg (p.Pro1980Arg), p.Ser2082Thr (p.Ser2063Thr), p.Leu2197Trp (p.Leu2178Trp), p.Asp2317Glu (p.Asp2298Glu)] two nonsense [p.Lys396* (p.Lys377*), p.Ser2205* (p.Ser2186*)], one insertion [p.Glu1268_Asp1269ins (p.Glu1249_Asp1250)] and seven deletions [p.Leu882del (p.Leu863del), p.Met701del (p.Met682del), p.Leu1223del (p.Leu1204del), p.Trp1961_Tyr1962del (p.Trp1942_Tyr1943del) p.Glu1988del (p.Glu1969del), p.His1841del (p.His1822del), p.Ser2205del (p.Ser2186del)] were identified. Double mutations (p.Asp2317Glu; p.Thr696Ile) were observed in a moderate HA case. Mutations [p. Arg612Cys (p.Arg593Cys), p.Arg2326Gln (p.Arg2307Gln)] known to be predisposing to inhibitors to factor VIII (FVIII) were identified in two patients. 4.6% of the cases were found to be cross reacting material positive (CRM+ve). A wide heterogeneity in the nature of mutations was seen in the present study which has been successfully used for carrier detection and antenatal diagnosis in 10 families affected with severe to moderate HA.
